## Shortlist

### 1. HeyGen

AI avatar video, voice cloning and video translation into 175+ languages with lip sync.

**Where it improves on Synthesia:**
- [Unused credits: yes — Unused monthly credits carry into one further cycle, roughly 60 days in all, and annual subscribers accumulate theirs until renewal; everything unused is lost if you drop to Free.](https://help.heygen.com/en/articles/15126059-how-to-use-credits-on-heygen)
- [Commercial use: yes — From the cheapest paid plan upward you own what you generate and may publish it commercially: the terms give Creator, Pro and Business users all rights in their output for their own purposes including commercial ones, while the Free plan's separate clause restricts output to personal, non-commercial evaluation.](https://www.heygen.com/terms)
- [Pronunciation fixes: yes — Brand Glossary holds pronunciation and translation of named terms steady across a whole project with forced translations and protected terms; it is off on Free and starts on Creator.](https://help.heygen.com/en/articles/10029081-how-to-get-started-with-video-translation)

**Trade-offs against Synthesia:**
- [Promotion and regular price: no — none. The price shown first is the plain month-to-month rate: each plan card opens with its Monthly control selected at $29, $49 and $149, and only switching the card's own control to Yearly drops Creator to $24 a month billed as $288 for the year, advertised as two months free rather than as an introductory discount.](https://www.heygen.com/pricing)
- [Voices that use more: partial — The newer engines burn the allowance far faster, 48 credits a minute for Avatar V against 4 for an Avatar III video look, and Precision dubbing costs 10 a minute against Speed's 6; no per-voice rate difference is published.](https://help.heygen.com/en/articles/15126059-how-to-use-credits-on-heygen)
- [Audio you get: partial — You can download just the audio or the captions SRT beside the video, and MP3 or MP4 from the podcast and cloning flows; audio-only export of a translation is Enterprise-only, and no bitrate is published for app exports.](https://help.heygen.com/en/articles/9834825-how-to-download-or-export-a-video)

### 2. Narakeet

Duration-priced browser voice-over and narrated-video maker with non-expiring capacity.

**Where it improves on Synthesia:**
- [Past your allowance: yes — Additional capacity is sold as non-recurring top-up credit; the stated 30-minute pack costs twenty cents per minute.](https://www.narakeet.com/docs/pricing/)
- [Unused credits: yes — Purchased capacity remains available for future use rather than expiring at a monthly billing boundary.](https://www.narakeet.com/docs/pricing/)
- [Commercial use: yes — Any paid commercial account permits commercial publishing, while free-account materials remain limited to personal evaluation.](https://www.narakeet.com/docs/usage-rights-copyright/)

**Trade-offs against Synthesia:**
- [Promotion and regular price: no — none — Narakeet describes its public capacity purchase as a one-time payment, not a promotion or recurring subscription.](https://www.narakeet.com/docs/pricing/)
- [Voices that use more: no — Charging depends on output length alone, not on which of the 900 voices you pick, so newer or more expressive voices do not drain the allowance faster.](https://www.narakeet.com/docs/pricing/)
- [Video dubbing: partial — Narakeet makes synchronized dubbed tracks from translated subtitle files, but documents choosing a target voice rather than cloning the speaker.](https://www.narakeet.com/create/ai-dubbing.html)

### 3. Murf AI

Voice-over Studio with timeline video syncing, downloadable audio, dubbing, and a public API.

**Where it improves on Synthesia:**
- [Unused credits: yes — Unused Studio time can roll into only the immediately following renewal cycle and is lost after cancellation.](https://help.murf.ai/vgt-carry-forward)
- [Commercial use: yes — Creator includes commercial rights, while the free trial explicitly lacks commercial rights and downloadable files.](https://murf.ai/pricing)
- [Pronunciation fixes: yes — Custom pronunciations can be saved and applied across a project; shared pronunciation libraries are Enterprise-only.](https://help.murf.ai/pronunciation)

**Trade-offs against Synthesia:**
- [Voices that use more: partial — On the API the studio-quality text to speech model costs three times the newest Falcon 2.1 model per thousand characters, so the choice of model changes what speech costs; Studio subscriptions instead meter hours of voice generation with no per-voice rate stated on this page.](https://murf.ai/pricing)
- [Instant cloning: partial — Instant voice cloning uses one short reference recording but is Enterprise API access that must be enabled for the workspace.](https://help.murf.ai/are-there-any-specifications-for-recording-the-voice-data)
- [Consent of the voice’s owner: partial — Enterprise cloning rules require ownership or clear documented consent for the voice submitted to Murf.](https://help.murf.ai/are-there-any-specifications-for-recording-the-voice-data)

### 4. Akool

AI video suite with video translation, lip sync, text to speech, voice cloning and a voice changer.

**Where it improves on Synthesia:**
- [Unused credits: partial — Subscription credits are issued per billing period and expire unused on every self-serve plan; only Enterprise is listed with credits that do not expire, so rollover is a higher-tier property.](https://www.akool.com/refund-policy)
- [Your voice trains their models: no — The Terms of Service rule out training on customer material outright, so there is nothing to opt out of; the content policy repeats the guarantee for uploaded and generated content.](https://www.akool.com/terms-of-service)
- [How long a video you can dub: yes — Each plan caps the source video it will translate: 5 minutes on Free and Starter, 30 on Pro, 60 on Pro Max and 120 on Business, with upload quality rising from 4K to 8K.](https://www.akool.com/pricing)

**Trade-offs against Synthesia:**
- [Several speakers: partial — Video Translation detects multiple speakers in an uploaded video so each gets its own translated voice, but no page read describes assigning several voices inside one text to speech script.](https://www.akool.com/apps/video-translation)
- [Consent of the voice’s owner: partial — Akool requires that you be authorized to use any voice or likeness you upload and bans harmful impersonation, but documents no verification step or consent proof before a clone is trained.](https://help.akool.com/trust-and-safety)
- [Editing the translation: partial — A proofreading editor lets you correct the translated script before the final render, but the comparison table shows no Proofread Editor on the Free plan and the cards gate proofread access at Pro.](https://www.akool.com/apps/video-translation)

### 5. Speechma

Free text to speech and creator audio tools with no account or credit card.

**Where it improves on Synthesia:**
- [Commercial use: yes — Commercial use is included for generated audio when the buyer owns rights to source text, recordings, and videos.](https://speechma.com/faq)
- [Your voice trains their models: no — Your recordings are processed only to make the result you asked for, are not kept after processing, and infrastructure partners may not use them for their own purposes.](https://speechma.com/privacy)
- [How long a video you can dub: yes — Free dubbing accepts MP4, MOV, or WEBM files up to 60 MB and offers nine target languages.](https://speechma.com/ai-dubbing)

**Trade-offs against Synthesia:**
- [Promotion and regular price: no — none: the free price is permanent rather than an introductory rate, and the vendor states there is no trial and no card involved at all.](https://speechma.com/)
- [Voices that use more: no — Premium HD voices do not consume more allowance: they are free on the site, and every API plan includes the full voice catalog at one character rate.](https://speechma.com/api/)
- [Lip sync: no — The dubbed-video tool replaces speech in another language but explicitly leaves the speaker’s lip movements unchanged.](https://speechma.com/ai-dubbing)

[View Speechma](https://dubsheet.com/speechma)

### 6. Voicemaker

Credit-metered AI text-to-speech studio with 2,000+ voices, voice cloning, speech-to-speech and SRT export.

**Where it improves on Synthesia:**
- [Unused credits: partial — Rollover is plan-dependent: Starter and Creator get none, Pro monthly carries credits one billing cycle, Teams and Business up to three months.](https://voicemaker.in/faq)
- [Commercial use: yes — Commercial publishing rights begin with Starter and apply to every paid Voicemaker plan.](https://voicemaker.in/pricing)
- [Pronunciation fixes: yes — A Pronunciation Editor locks how names, brands and technical terms are spoken and keeps that choice consistent across projects.](https://voicemaker.in/)

**Trade-offs against Synthesia:**
- [Promotion and regular price: no — none — Starter is shown as a monthly subscription, while annual billing is displayed separately.](https://voicemaker.in/pricing)
- [Video dubbing: partial — The site advertises AI Dubbing into 130+ languages that keeps tone and can use cloned voices, but its billing meters this only as per-second speech-to-speech redubbing and no video upload or export step is documented.](https://voicemaker.in/)
- [API: partial — A full REST API for text-to-speech, speech-to-speech and speech-to-text exists, but only on a separate pay-as-you-go developer platform rather than inside the subscription plans.](https://voicemaker.in/faq)

### 7. Fish Audio

Expressive text-to-speech, voice cloning and long-form studio with a credit-metered API.

**Where it improves on Synthesia:**
- [Pronunciation fixes: yes — Reusable pronunciation dictionaries are built and published in the web app and then referenced from text to speech requests, so one fix applies across a whole project.](https://docs.fish.audio/overview/platform)
- [Platforms: yes — web: the whole product runs in the browser with no install, and every tool from cloning to Story Studio is reachable from the signed-in web app.](https://docs.fish.audio/overview/platform)

**Trade-offs against Synthesia:**
- [Your voice trains their models: yes — The terms authorize Fish Audio to train its models on your content and usage data, and the only published way out is the Enterprise plan's zero data retention, not a self-serve switch.](https://fish.audio/terms/)
- [Video dubbing: no — Audio Translation transcribes and translates speech into text you read, not dubbed audio in the speaker's voice, and the product takes audio files rather than video.](https://fish.audio/translate-audio/)
- [Lip sync: partial — Lip-sync exists for avatars built from your images and videos against a Fish Audio voice, and needs a Plus plan or higher; it is not offered as lip matching for a translated dub.](https://docs.fish.audio/overview/mcp)

### 8. TopMediai

AI studio for text to speech, voice cloning and video dubbing on one shared credit balance.

**Where it improves on Synthesia:**
- [Professional cloning: yes — A separate High-Precision mode trains on longer recordings and is described as capturing speaking style, emotion and rhythm rather than timbre alone.](https://www.topmediai.com/app/ai-voice-cloning/)
- [Platforms: yes — web - the voice tools are browser-based with nothing to install, and two cloning modes are flagged as desktop-only inside that web app.](https://www.topmediai.com/app/text-to-speech/)
- [AI labelling: yes — The terms commit the vendor to marking generated content as AI-made and forbid users removing the mark, though no file-checking tool is offered.](https://www.topmediai.com/terms-conditions/)

**Trade-offs against Synthesia:**
- [Consent of the voice’s owner: partial — The terms make you warrant that the voice owner authorized the clone, but describe no verification step or proof the vendor collects before cloning.](https://www.topmediai.com/terms-conditions/)
- [Lip sync: partial — The dubbing pipeline is described as analyzing lip movements to time the new audio against them, which is sync rather than regenerating the mouth itself.](https://www.topmediai.com/ai-dubbing/)
- [API: partial — A documented speech API exists but is a separate product line: the vendor states plainly that it is not included in the text-to-speech plans and must be bought on its own.](https://www.topmediai.com/api/text-to-speech-api/)

[View TopMediai](https://dubsheet.com/topmediai)

### 9. Typecast

Expressive AI voice generator with emotion controls, voice cloning and a developer speech API.

**Where it improves on Synthesia:**
- [Commercial use: yes — A commercial license starts on the cheapest paid Studio plan, Basic at $5 a month, which also makes attribution optional; the $0 Free plan carries no commercial license and requires attribution on everything downloaded.](https://typecast.ai/pricing/)
- [Pronunciation fixes: yes — The vendor says you can change how words are spoken along with pitch and rhythm, and a separate text preprocessing library normalizes numbers, dates and phone numbers.](https://typecast.ai/text-to-speech/)
- [Platforms: yes — web, ios, android: the studio runs in a browser and the mobile app is on both stores, with projects syncing across devices and no desktop app offered.](https://typecast.ai/)

**Trade-offs against Synthesia:**
- [Instant cloning: partial — Instant Cloning needs five seconds of audio and appears from Basic upward with one slot, so the Free plan gets no cloning at all.](https://typecast.ai/pricing/)
- [Captions and subtitles: partial — Subtitles come only from the developer tools, which write SRT, WebVTT or raw JSON timings beside the audio; the studio plans never mention captions.](https://typecast.ai/docs/cli-reference/timestamps-captions)
- [Voice to video: partial — A built-in video editor pairs the voice with visuals and music and exports up to 4K, but export quality and watermark removal depend on the plan.](https://typecast.ai/text-to-speech/)
