Hume AI ranks #9 of 10 in AI voice generation, with an Alt Score of 85. It is proprietary, freemium from $3/mo and available on the web. 8 of 9 checklist rows are verified against a public source. Source: https://altcatalog.com/alternatives/hume-ai/ Category: AI voice generation ## Overview - **Who it's for**: Developers and product teams building voice AI features — conversational agents, customer service bots, audiobooks, podcasts, game and character voices — who need expressive, emotionally aware speech generation or real-time spoken dialogue. - **What you get**: Octave, a speech-language text-to-speech model that supports voice design from text prompts, voice cloning from a recorded or uploaded audio sample, and voice conversion of existing audio; and the Empathic Voice Interface (EVI), a real-time speech-to-speech conversational AI that measures vocal prosody. Access is via REST/streaming APIs with TypeScript, Python, and .NET SDKs, plus a web platform (app.hume.ai) for managing voices and configurations. - **How it works**: Users create or clone voices in the Hume Platform or via the Voices API, then call the TTS API (including streaming endpoints) to synthesize speech with optional acting instructions, or connect to EVI over a WebSocket-based control plane where Hume's models transcribe user speech, analyze its tune/rhythm/timbre, generate a language-model response, and stream back synthesized voice audio. ## Profile - **License**: Proprietary (verified 2026-07-30) - **Pricing model**: Freemium (verified 2026-07-30) - **Starts at**: $3/mo (verified 2026-07-30) - **Platforms**: Web - **Status**: active (verified 2026-07-30) ## Ranked alternatives | # | App | Alt Score | Licence | Platforms | |---|-----|-----------|---------|-----------| | 1 | [Cartesia](https://altcatalog.com/alternatives/cartesia.md) | 100 | Proprietary | ? | | 2 | [Speechify](https://altcatalog.com/alternatives/speechify.md) | 100 | Proprietary | iOS, Android, macOS, Windows | | 3 | [Camb.ai](https://altcatalog.com/alternatives/camb-ai.md) | 95 | Proprietary | Web | | 4 | [ElevenLabs](https://altcatalog.com/alternatives/elevenlabs.md) | 95 | Proprietary | Web, iOS, Android | | 5 | [Murf](https://altcatalog.com/alternatives/murf.md) | 95 | Proprietary | Web | | 6 | [Resemble AI](https://altcatalog.com/alternatives/resemble-ai.md) | 90 | MIT | Web, Browser extension | | 7 | [Fish Audio](https://altcatalog.com/alternatives/fish-audio.md) | 85 | ? | Web | | 8 | [WellSaid](https://altcatalog.com/alternatives/wellsaid.md) | 85 | Proprietary | Web | | 9 | [Lovo (Genny)](https://altcatalog.com/alternatives/lovo.md) | 80 | ? | Web | Alt Score = Verified coverage (90%) + Visibility (10%).
