The trade-offs

Strengths and Limitations

Fathom

Strengths

Free plan carries unlimited recordings, transcription and AI summaries
Records without a bot in the call from the desktop app, or with one
Transcripts in 38 languages
Documented REST API with webhooks, SDKs and an MCP server

Limitations

Transcription and summarisation only, with no voice synthesis, cloning or dubbing
Summary translation covers six languages against the 38 it transcribes
Team and Business plans carry a two-user minimum
CRM field sync, coaching metrics and custom summaries start on the Business plan

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
