Full Comparison

Criterion Google Cloud Text-to-Speech Resemble AI
Starting price 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 tier (Flex, pay as you go); detection plans from $280 / month The published plans cover deepfake detection, watermarking, identity and meetings, plus platform and API access. Flex has no subscription fee and is billed from prepaid credits. Team is $350 / month billed monthly, or $280 billed annually, and carries 5 seats; Business is $1,000 / month, or $800 billed annually, with 20 seats. Generative speech, voice cloning and speech-to-speech are quoted separately.
Free trial Free monthly allowance: 4 million characters on Standard and WaveNet voices, 1 million on Chirp 3 HD, Neural2, Polyglot and Studio voices Not stated
Commercial use Not stated Paid
Output Synthesised speech, single request, streaming or long-form, as LINEAR16, MP3, OGG_OPUS, ALAW, MULAW, PCM or M4A Voice cloning, speech-to-speech, Voice Design from prompts, real-time
API Yes, the Cloud Text-to-Speech API with client libraries and a command-line path Yes
Languages Google's own figure is 220+ voices across 40+ languages 100 languages and regional dialects on the managed platform, voice cloning in 23
Hosting Cloud (Google Cloud), with a global endpoint and regional endpoints Cloud, with containerised on-premise and air-gapped installs via Docker and Kubernetes
Voice cloning 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 Yes, professional cloning with consent verification
Real-time use Yes, bidirectional streaming synthesis for live use, alongside ordinary single requests and a separate long-form path for large documents Yes
Speech-to-speech and dubbing No. This service synthesises speech from text only. Recognition is the separate Speech-to-Text service and translation the separate Translation AI service Yes, converts a recording into another voice while keeping pacing, emphasis and inflection, with streaming on all model versions
Editing and controls 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 Voice Design from prompts
Consent and trust 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 Consent verification, plus deepfake-detection tools

Support Not stated Email helpdesk, Community forum
Onboarding Documentation and knowledge base Documentation and knowledge base
Company size more entries Freelancers, Small and mid-sized, Enterprise Small and mid-sized, Enterprise

The trade-offs

Strengths and Limitations

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

Resemble AI

Strengths

  • Professional cloning with consent verification
  • Speech-to-speech and Voice Design
  • Trust and security tools

Limitations

  • Public generative text-to-speech pricing is opaque, verify with a quote
  • More developer and security oriented
