Full Comparison

Criterion Speechmatics Vozo
Starting price lower value From $0.129 / hour of audio Pro tier rate, billed to the second with no commitment. Volume discounts of 20% apply automatically above 500 hours per month for each speech-to-text type, with further discounts above 24,000 hours a year. One credit equals one dollar. 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 Free tier with $100 in credit, no card required Free tier with 20 AI points, up to 3 projects
Commercial use Yes, usage-based Not stated
Output Transcripts, translations and synthesised speech Dubbed and lip-synced video, translated subtitles and translated on-screen text

Voice cloning No, the text-to-speech API ships four fixed voices, sarah and theo in British English and megan and jack in American English, and the documentation describes no custom or cloned voice; speed, pitch and emphasis are not adjustable either 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, streaming transcription returned in under a second, alongside batch transcription of recorded files 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
Speech-to-speech and dubbing Audio translation across 69 language pairs, returned as translated transcript rather than dubbed audio; a Voice Agent API is in early access Yes, AI dubbing of uploaded video, with lip sync from the Creator plan
Editing and controls Speaker diarization and identification, custom dictionary, language identification, background speech filtering, and speech intelligence for summaries, sentiment, topics and auto-chapters 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 Data is not logged as standard; container, Kubernetes, virtual appliance and on-device deployment keep audio inside your own infrastructure 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

Speechmatics

Strengths

  • 55+ languages with explicit accent, dialect and code-switching coverage
  • Runs in the cloud, in containers, on-premises or on-device
  • $100 in credit to start, with no card required
  • Data is not logged as standard

Limitations

  • A developer API rather than a ready-made voice studio
  • Text-to-speech on the free tier covers English only
  • The Voice Agent API is still in early access
  • Volume discounts start at 500 hours a month, so small workloads pay the full rate

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
