What is Hume AI?
Hume AI is an artificial intelligence platform focused on understanding and generating human emotion through voice and facial expressions. The company develops tools that allow machines to perceive emotional cues and respond in ways that align with human affective states. Its Empathic Voice Interface (EVI) provides natural conversational capabilities, detecting and expressing emotion through tone and context, while its Text-to-Speech API converts written text into expressive, emotionally nuanced speech.
Hume AI’s Expression Measurement suite captures and analyzes emotional responses from audio and video inputs, enabling developers, researchers, and businesses to quantify user sentiment and engagement. The technology is grounded in scientific research on human expression, making it applicable across healthcare, education, customer experience, and conversational AI systems.
By combining emotion recognition with generative speech, Hume AI aims to create more natural, empathic interactions between humans and AI systems, supporting the next generation of emotionally intelligent applications.

Hume AI is a research lab and technology company focused on building AI systems that understand and respond to human emotion – in other words, emotional intelligence for machines. According to the company: “Our mission is to ensure that artificial intelligence is built to serve human goals and emotional well-being.”
By enabling machines to measure and generate emotional nuance via voice, speech, facial expression or text, it aims to tackle the problem of “dry,” context-blind, emotion-unaware AI experiences.
When you create voice-based content, the problem is that traditional text-to-speech engines often feel robotic, flat, or context-unaware. That can break engagement or reduce emotional impact. Hume AI’s TTS engine – called Octave – solves that by being a “voice-based LLM” that understands the meaning of words in context, and can therefore predict emotions, cadence, and delivery style.
Key differentiators:
- You can instruct it to “sound sarcastic,” “whisper fearfully,” etc.
- It supports ultra-low latency streaming (approx. 200ms) for applications like voice assistants, avatars, phone calls.
- It supports many languages (11+ listed).
The “Empathic Voice Interface,” referred to as EVI, is a speech-to-speech foundation model built by Hume AI. It aims to support highly realistic voice interactions, where a user speaks and the system responds in voice – with nuance, style, possibly cloned voice, tuned tone, and conversational context.
You’d use EVI in applications such as:
- Voice assistants or chatbots that speak back with personality
- Game characters or AI companions that speak fluidly
- Real-time voice interfaces in customer service, phone calls, etc
Features:
Hume AI’s “Expression Measurement” product enables developers to measure human emotional expression via one API across multiple modalities – speech prosody, voice, facial expression, video, text.
Use cases include:
- Analysing customer support calls to detect frustration, confusion, satisfaction
- Evaluating videos for emotional tone in media & entertainment
- Voice-based wellness or feedback apps that track user affect over time
- The product is built on “10+ years of research, millions of proprietary data points, and over 40 publications” to support high-dimensional understanding of emotion rather than simplistic categories.
Hume AI offers tiered pricing across Free, Starter, Creator, Pro, Scale, Business and custom Enterprise plans.
Highlights:
- Free plan: $0/month with limited usage (e.g., ~10 minutes of text-to-speech).
- Starter plan: $3/month (first month 50% off) with ~30 minutes TTS, 40 minutes speech-to-speech included.
- Higher tiers scale to millions of characters/minutes for TTS, configurable usage for speech-to-speech, voice cloning, team collaboration, commercial licenses.
- The Expression Measurement product is priced pay-as-you-go — e.g., $0.0213/min for audio only, $0.015/min for video only.
Implication:
Hume AI demonstrates strong expertise and trust by:
- Basing its mission on emotion science and ethical AI, acknowledging the “AI alignment” challenge and emphasising human well‐being.
- Backing its products with research: e.g., for the Expression Measurement product site states “10+ years of research… over 40 publications in leading journals.”
- Offering compliance for enterprise plans (SOC 2 Type II, GDPR, HIPAA) in their pricing page.
These elements establish Hume AI as both technically rigorous and ethically oriented – helpful in building confidence for enterprise decision-makers.
Yes, Hume AI is designed to support both ends of the spectrum.
- For startups or creators: the Free/Starter/Creator tiers allow low-cost entry, enabling experimentation with expressive voice or emotion measurement features.
- For fast-growing teams: as usage scales you can upgrade to higher tiers (Pro, Scale) with support for millions of characters/minutes, team seats, voice cloning, commercial licenses.
- For large enterprises: the Business or custom Enterprise plan provides unlimited usage, high concurrency (e.g., 30+ connections), full API/SDK integrations, compliance (e.g., HIPAA) and dedicated support.
Conclusion
Before committing, you should consider:
- While the engine supports many languages (11+ spoken languages listed), you’ll want to check if your target language/localisation is fully supported.
- Voice cloning (and unlimited usage) is only available in the higher tiers – lower tiers may have restrictions (“Create only” vs “create and use”).
- Usage-based pricing for heavy usage (especially speech-to-speech or expression measurement) means cost will scale with volume – you should model your expected minutes/characters.
- As with any advanced voice/emotion AI, integration complexity (SDKs, latency, tuning of tone/instruction) may require some development effort – it’s more than plug-and-play in simple cases.
By verifying these factors ahead of time, you can ensure Hume AI meets your budget, language and integration needs.
