Hume AI

Starter at $3 per month covers light personal projects and testing, while Creator at $14 per month raises volume for regular production work. Pro and Scale tiers above them bill on usage for teams running API workloads, with Octave 2 character pricing from about $7.60 per million characters, so growing applications scale predictably without per seat surprises.

Yes. Voice design accepts a prompt describing age, accent, and register, then generates matching voices without any casting or recording session. Because voice cloning is included on every plan, you can either describe a brand new speaker or replicate an approved one, which keeps character production fast for narration series, games, and branded content.

Yes. Hume connects through a REST API, Python SDK, and WebSocket streaming, with documented integrations for Twilio phone systems and LiveKit real time sessions. That combination makes it practical for support hotlines, voice agents, and live applications where generated speech needs to start within milliseconds of a user request.

EVI, the empathic voice interface, is built exactly for that use case: real time agents that adapt their tone to user emotion during conversation. The tooling leans developer oriented with less polish for casual creators, but teams building support or companion agents get the most emotionally expressive speech in blind comparisons at pricing that undercuts premium TTS rivals.

Octave acts emotion and follows direction written into the script, so one line can read nervous, excited, or weary without a re recording session. Voice design from prompts plus cloning on every plan covers cast building for games, audiobooks, and serialized fiction. Quality varies on unusual voice prompts, so test directions on the free tier before upgrading.

Hume AI is a voice platform built on emotion research, with Octave for expressive text to speech, EVI for real time empathic voice interfaces, and an API that developers use for agents, narration, and interactive products.

Subscription tiers run from a Starter plan around 3 dollars per month through Pro at 70 dollars and Scale at 200 dollars, and API usage for Octave 2 costs about 7.60 dollars per million characters, with voice cloning included on every plan.

Octave treats the script like an acting direction, generating voices with personality from a prompt and following inline direction such as sarcasm or excitement, so output sounds performed rather than read.

EVI is the Empathic Voice Interface, a real time speech model that responds to how a user sounds as well as what they say, adjusting its own prosody, which developers use for support agents and companion products.

Hume leads on expressiveness per dollar and voice design from prompts, while ElevenLabs offers a broader creator ecosystem and more polished consumer tools, so teams pick based on whether emotion or ecosystem matters more.

Yes, voice cloning is included on every plan, including the low cost tiers, which is unusual in the category.

Developers and teams building voice first products where expression matters, such as agents, companions, audiobooks, and games, rather than casual users who want a one click voiceover.

Create an account, generate an API key, and call the Octave 2 text to speech endpoint or the EVI real time socket from the SDKs. Octave 2 usage starts at about $7.60 per million characters, subscription tiers run $3 per month for Starter and $14 per month for Creator with usage based Pro and Scale tiers above that, and voice cloning is included on every plan so you can test with your own voice immediately.
