Criterion Camb.ai Google Cloud Text-to-Speech
Starting price Free tier; paid from $5 / month Plans are metered in credits, so cost depends on usage. lower value Free tier, then from $4 per 1 million characters Pay-as-you-go by characters sent for synthesis, counting spaces, newlines and most SSML tags, with a free monthly allowance per voice type. Standard and WaveNet $4 per 1 million characters, free to 4 million a month. Neural2 and Polyglot $16, Chirp 3 HD $30 and Studio $160, each free to 1 million a month. Instant Custom Voice $60 with no free allowance. Gemini-TTS is billed per token instead, from $0.50 per 1 million input text tokens and $10 per 1 million output audio tokens, also with no free allowance.
Free trial Free tier with 2,000 credits per month Free monthly allowance: 4 million characters on Standard and WaveNet voices, 1 million on Chirp 3 HD, Neural2, Polyglot and Studio voices
Output AI dubbing, text-to-speech and translation across many languages Synthesised speech, single request, streaming or long-form, as LINEAR16, MP3, OGG_OPUS, ALAW, MULAW, PCM or M4A
API Yes Yes, the Cloud Text-to-Speech API with client libraries and a command-line path
Hosting Not stated Cloud (Google Cloud), with a global endpoint and regional endpoints
Voice cloning Yes, from a reference file of 10 to 30 seconds of clear speech Yes, Chirp 3 Instant Custom Voice builds a personal voice model from a short high-quality recording, usable afterwards for streaming and long-form synthesis. Access is restricted to allow-listed customers and is arranged through the sales team rather than self-service. A cloning key created for en-US can also speak German, US and European Spanish, Canadian and European French and Brazilian Portuguese
Real-time use Yes, real-time dubbing with DubStream Yes, bidirectional streaming synthesis for live use, alongside ordinary single requests and a separate long-form path for large documents
Languages Depends on the model: 33 with MARS-Flash and MARS-Pro, 141 with MARS-Instruct, 312 in the 8.1 beta models Google's own figure is 220+ voices across 40+ languages. Chirp 3 HD ships 30 named voices, with Punjabi (India) and Chinese (Hong Kong) still in preview, and Instant Custom Voice supports a shorter list that includes Arabic, Bengali, Mandarin, several English variants and French
Speech-to-speech and dubbing Yes, on-demand (DubStudio) and real-time (DubStream) dubbing No. This service synthesises speech from text only. Recognition is the separate Speech-to-Text service and translation the separate Translation AI service
Editing and controls Yes, inline emotion and non-verbal tags, CMU-phoneme pronunciation, SSML-style pauses, and broader delivery instructions with MARS-Instruct SSML, pace control from 0.25x to 2x, experimental pause tags and custom pronunciation in IPA or X-SAMPA phonetic encoding, device profiles that tune output for the playback hardware, and text-based prompting on the Gemini-TTS models, which take a written description of the delivery rather than markup
Consent and trust The terms make the customer solely responsible for the permissions and consents covering every voice recording and video it uploads, and impersonating another person is prohibited; no consent check or verification step is documented in the product Instant Custom Voice sits behind an allow list that is granted by the sales team, and enrolment requires the speaker to record a consent statement that Google supplies in the language being cloned, in English: "I am the owner of this voice and I consent to Google using this voice to create a synthetic voice model." The recording is part of the enrolment, so a voice cannot be cloned from found audio

The trade-offs

Strengths and Limitations

Camb.ai

Strengths

  • Real-time dubbing (DubStream) and on-demand dubbing (DubStudio)
  • MARS speech models tuned for conversation, dubbing and narration
  • Broad language coverage for media and sports localization

Limitations

  • Priced in credits, so cost depends on usage
  • Aimed at localization and dubbing more than general voiceover

Google Cloud Text-to-Speech

Strengths

  • One API spans cheap legacy voices at $4 per million characters and current HD voices at $30
  • Gemini-TTS takes a written prompt for the delivery instead of hand-written SSML markup
  • Free monthly character allowance on every voice type except Gemini-TTS and custom voices
  • Bidirectional streaming, single request and long-form synthesis from the same service
  • Voice cloning requires a recorded consent statement from the speaker, in their own language

Limitations

  • Text to speech only: recognition and translation are separate Google Cloud services
  • Instant Custom Voice is restricted to allow-listed customers and goes through sales
  • Studio voices cost $160 per million characters, forty times the Standard rate
  • Gemini-TTS is billed per token rather than per character, so the two price models do not compare directly
  • The overlapping generations of voice model take some reading before the right one is obvious
