Full Comparison
| Criterion | Google Cloud Text-to-Speech | Voicemod |
|---|---|---|
| Starting price | 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. | Not stated |
| 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 version for Windows and Mac |
| Output | Synthesised speech, single request, streaming or long-form, as LINEAR16, MP3, OGG_OPUS, ALAW, MULAW, PCM or M4A | A changed voice delivered live through a virtual microphone, plus soundboard clips and recordings |
| API | Yes, the Cloud Text-to-Speech API with client libraries and a command-line path | Yes, a Control API with an API key and bindings for Unity, JavaScript, C/C++ and Java |
| Hosting | Cloud (Google Cloud), with a global endpoint and regional endpoints | Desktop application for Windows and Mac, a mobile soundboard app, and the Voicemod Key device for consoles |
| 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. Voicelab builds a voice by layering more than 140 effects over your own, and the vendor publishes no way to reproduce a specific person's voice |
| Real-time use | Yes, bidirectional streaming synthesis for live use, alongside ordinary single requests and a separate long-form path for large documents | Yes, and it is the whole product: a virtual microphone changes the voice live in Discord, OBS, Fortnite, Valorant, Minecraft, League of Legends and more than 30 other applications |
| 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 | No published language list. The vendor states the AI voices were built from data recorded by English-speaking voice actors, so English gives the best results, and that other languages can still work but the AI may have difficulty with some of their sounds and articulations |
| 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 | Real-time voice changing transforms your own speech into another voice; no dubbing or translation is published |
| 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 | Over 200 AI voices, Voicelab for building or remixing voices from more than 140 effects including pitch, tone, Reverb, Delay and Robotifier, plus a soundboard with keybinds, a recorder for YouTube and in-game audio and a 30-second instant replay |
| 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 | The vendor states its AI voices are trained by professional voice actors and carry a Fairly Trained certification |

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
Voicemod
Strengths
- Works live in more than 30 games and applications through a virtual microphone
- Voicelab builds custom voices from over 140 effects and publishes them to the community
- Control API drives the app from Unity, JavaScript, C/C++ or Java
- AI voices are trained with professional voice actors under a Fairly Trained certification
- Free version for Windows and Mac
Limitations
- No voice cloning: Voicelab shapes effects rather than reproducing a specific person's voice
- Plan amounts are not published on the site
- Built around gaming, streaming and chat applications rather than rendered audio files
