| Hosting | Cloud (Google Cloud), with a global endpoint and regional endpoints | Not stated |
| 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, voice cloning in Speechify Studio, and zero-shot cloning on the developer platform that turns a short reference clip into a reusable voice ID |
| Real-time use | Yes, bidirectional streaming synthesis for live use, alongside ordinary single requests and a separate long-form path for large documents | Yes, the developer models are streaming-native with a claimed time to first byte under 300ms, and a separate voice agents API adds tools, memory and telephony |
| 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 | 1,000+ voices in 60+ languages in the reader; the developer models cover six validated locales, namely US English, German, Mexican Spanish, French, Italian and Brazilian Portuguese |

| 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 | Playback up to 4.5x with synchronized highlighting, plus captions in Studio and SSML emotion control on the developer models across neutral, calm, cheerful, energetic and sad |
| 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 | Cloning is consent-first: a voice is built from a consented reference clip, and the company publishes its policy on keeping cloned voices out of election misinformation |

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
Speechify
Strengths
- Best for turning reading material into audio
- Accessibility focus
- Popular with creators
Limitations
- Free tiers lack commercial rights
- More consumer reader than production studio
