Hume AI

Application

Creator StudioApplication

Creator Studio is Hume's web application, hosted at app.hume.ai, for turning written documents into narrated audio: 'From document to audio, effortlessly. Import your content, assign voices, add acting directions, and export production-ready audio.' Hume targets it at creators producing audiobooks, videos, podcasts, documentaries, e-learning courses and corporate training that need multi-voice narration with emotional direction.

API service

Empathic Voice Interface (EVI)API service

Empathic Voice Interface (EVI) is Hume's real-time speech-to-speech voice AI API, described in Hume's docs as 'an advanced, real-time emotionally intelligent voice AI.' The product page markets it as a way to 'Build voice-first AI experiences that understand and respond to human emotions' and states it 'works seamlessly with Claude, GPT, Gemini, Grok, Kimi K2, Llama, and more' - layering voice on top of third-party language models rather than supplying its own. It is billed per conversation minute on Hume's public plans.

Expression Measurement APIAPI service

The Expression Measurement API measures emotional and vocal expression in speech, marketed as 'Measure expression in voice, offline or in real time.' Hume describes two endpoints on the one page: 'The Tagger API returns 600+ expression and voice dimensions from any audio, at scale. The Prosody API delivers real-time emotional expressions during live conversations.' Measured dimensions include emotion categories, speaking styles, vocal qualities such as pace, warmth and hesitation, and expression intensity with confidence scores.

Human Feedback APIAPI service

The Human Feedback API sells human evaluation of voice and conversational AI as an API call, marketed as 'One API call. Real human ratings.' and 'Plug human evaluation into your pipeline. Audio in, structured results out.' It supports three study types - live conversations with AI models, single-sample audio ratings with custom questions, and side-by-side A/B comparisons - with Hume handling participant recruitment, quality control and fraud detection. Hume states it powers 'evaluation for Hume's own frontier voice models.'

Octave TTSAPI service

Octave TTS is Hume's text-to-speech API, which Hume's documentation calls 'the first text-to-speech system built on LLM intelligence.' The marketing page positions it as 'Text-to-speech with emotional intelligence' that generates 'expressive, natural-sounding speech that conveys the full range of human emotion,' with SDKs for Python, TypeScript, .NET and Swift and streaming audio output. It is billed by characters on Hume's public self-serve plans.

Platform

Kairos PlatformPlatform

Evaluation platform for voice agents: it builds evaluation suites from real-world use cases, simulates agent-to-agent and human-to-agent conversations against any voice model, and tracks regressions over time.
