Full Comparison
| Criterion | Deepgram | Vozo |
|---|---|---|
| Starting price | Usage-based, pay-as-you-go No minimums and no expiry. Speech-to-text from $0.0048 / minute on Nova-3 monolingual streaming, text-to-speech from $0.0150 / 1,000 characters on Aura-1, and the Voice Agent API from $0.056 / minute. | Free tier; paid from $29 / month Plans are metered in AI points rather than flat minutes, so the cost follows how much dubbing, lip sync and visual translation a project uses. Each tier also caps video length and concurrent jobs. |
| Free trial | $200 in free credits to start, no credit card required | Free tier with 20 AI points, up to 3 projects |
| Commercial use | Yes, usage-based | Not stated |
| Output | Speech-to-text, text-to-speech and voice agents | Dubbed and lip-synced video, translated subtitles and translated on-screen text |
| API | Yes | Yes, on Enterprise plans |
| Hosting | Cloud, or self-hosted for in-region and in-house data control | Not stated |
| Voice cloning | No, the catalogue is fixed: 40+ prebuilt Aura-2 voices across English, Spanish, Dutch, French, German, Italian and Japanese, with no cloning or custom-voice product on the price list | VoiceREAL keeps the original speaker's tone in the dubbed track, VoiceNATIVE substitutes a native-accent voice; Voice Studio carries a library of 12,000+ voices |
| Real-time use | Yes, real-time streaming speech-to-text and text-to-speech, plus batch processing | Not a live pipeline: video is uploaded and rendered as a job, with one concurrent task on the free tier, 2 on Creator and 6 on Studio |
| Languages | 45+ languages for speech-to-text, with automatic language detection | 111 source and 165 target languages for translation and dubbing |
| Speech-to-speech and dubbing | No dubbing or translation product. Speech-to-speech runs as a pipeline through the Voice Agent API, which handles listening, thinking and speaking with configurable speech-to-text models, LLM providers and voices, plus function calling mid-conversation | Yes, AI dubbing of uploaded video, with lip sync from the Creator plan |
| Editing and controls | Voice selection, plus encoding, bit rate, container and sample rate on the output, streamed audio and callbacks. Aura-2 is built to read naturally without SSML markup, and speed and style can be changed mid-conversation without restarting the session | Yes, rewrite and redub a voiceover by editing text in Voice Studio, plus subtitle generation and embedding, on-screen text translation, and glossary and bulk upload on Studio |
| Consent and trust | SOC 2 Type 1 and 2, HIPAA, GDPR, CCPA and PCI compliant; self-hosting for in-house data control | Built with SOC 2 Type II controls and GDPR-aligned data handling, in the vendor's words; glossary and brand governance sit on Studio, and human review of the delivered output is an Enterprise add-on |

The trade-offs
Strengths and Limitations
Deepgram
Strengths
- Unified speech-to-text, text-to-speech and voice-agent APIs
- Real-time streaming with low latency for live applications
- Usage-based with $200 free credit and no card required
- Runs self-hosted for data control and compliance
Limitations
- Developer platform, not a consumer voice studio
- Several headline per-minute rates are promotional and sit below the list price, so the long-run cost depends on which rate applies
Vozo
Strengths
- Very broad language coverage, 111 source and 165 target languages
- Visual Translate rewrites on-screen text and keeps layout and animation
- Free tier covers a first project without a card
- Two dubbing modes, one keeping the original voice and one using a native accent
Limitations
- API access only on Enterprise plans
- Metered in AI points, so cost depends on the mix of dubbing, lip sync and visual translation
- Each tier caps video length, seats and concurrent jobs
- Lip sync and watermark-free export need at least the Creator plan
