Full Comparison
| Criterion | Google Cloud Text-to-Speech | Granola |
|---|---|---|
| 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, then $14 / user / month Business is $14 per user per month and Enterprise $35. The free Basic plan takes unlimited notes but limits how far back the history reaches. |
| Free trial | Free monthly allowance: 4 million characters on Standard and WaveNet voices, 1 million on Chirp 3 HD, Neural2, Polyglot and Studio voices | Free Basic plan with AI meeting notes, AI chat, shared folders and custom templates |
| Output | Synthesised speech, single request, streaming or long-form, as LINEAR16, MP3, OGG_OPUS, ALAW, MULAW, PCM or M4A | Transcripts and structured meeting notes with summaries and action items |
| API | Yes, the Cloud Text-to-Speech API with client libraries and a command-line path | Yes, on Business and Enterprise, alongside an MCP server |
| Hosting | Cloud (Google Cloud), with a global endpoint and regional endpoints | Cloud, with desktop apps for macOS and Windows, iOS and Android apps and Apple Watch support |
| 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 | No, Granola transcribes and summarises speech and does not synthesise or clone voices |
| Real-time use | Yes, bidirectional streaming synthesis for live use, alongside ordinary single requests and a separate long-form path for large documents | Yes, it transcribes the computer's own audio live during a call without joining as a bot, and on mobile it captures in-person meetings and phone calls |
| Languages | 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 | Multi-language support, included from the free Basic plan upwards |
| 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 | No dubbing or speech-to-speech translation |
| 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 | Customisable note templates, shorthand typed during the call expanded against the transcript, AI chat across the whole meeting history, shared folders and search |
| 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 | Opt-out of model training on every plan, with an org-wide opt-out, SSO, admin controls over sharing and API use, usage analytics, org-wide auto-deletion and an org-wide usage notification on Enterprise |
| MCP-ready | No | stated Yes |
| Deployment | Cloud (SaaS), Browser-based | Cloud (SaaS), Browser-based |
| Onboarding | Documentation and knowledge base | Not stated |
| Company size | Freelancers, Small and mid-sized, Enterprise | Freelancers, Small and mid-sized, Enterprise |
| Integrations | Not stated | Zoom, Google Meet, Microsoft Teams, Attio, Notion, Slack, HubSpot, Affinity, Zapier |

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
Granola
Strengths
- No bot joins the call, so nothing appears in the attendee list
- Expands shorthand typed during the meeting instead of replacing note-taking
- AI chat runs across the whole meeting history, not a single transcript
- Opt-out of model training on every plan, including the free one
- MCP server and API on Business, so meeting context reaches other AI tools
Limitations
- Capture depends on a machine being in the meeting, since it records local computer audio
- The free plan limits how far meeting history reaches back
- Integrations, API and MCP start on the Business plan
