Hume AI review
A flexible voice generator for expressive speech, cloning, and conversational APIs.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Hume AI provides expressive text-to-speech and conversational voice APIs for developers and organizations. Its platform combines a library of over 100 preset voices with prompt-based voice design, voice cloning, voice conversion, streaming generation, and file-based audio output. Acting instructions give creators control over delivery, while long-form continuation preserves context. It is a strong fit for conversational voice applications, narrated content, and teams that need both creative voice control and API access across web, iOS, macOS, and developer environments.
Pricing is structured for different usage levels. The Free plan costs $0 per month and includes text-to-speech, voice cloning, and 5 EVI minutes. Starter costs $3 per month with 40 EVI minutes. Creator costs $14 per month and adds a commercial license with 200 EVI minutes, followed by Pro at $70 with 1,200 minutes, Scale at $200 with 5,000 minutes, and Business at $500 with 12,500 minutes. The Enterprise plan offers custom usage, commercial licensing, voice cloning with API access, and listed SOC 2 Type II, GDPR, and HIPAA coverage. Commercial use begins with Creator, so Free and Starter are better suited to non-commercial work.
The standout capability is expressive synthesis: Octave speech-language technology is designed to control voice style, emotion, pacing, and delivery rather than only converting text into speech. Hume also supports voice conversion, long-form context preservation, and audio in MP3, WAV, and PCM formats. Integrations with Agora, LiveKit, Twilio, VAPI, and the Vercel AI SDK support realtime and application development workflows. Choose Hume AI if expressive conversational output and voice design matter; choose an alternative if commercial rights are required below Creator or if a simpler text-to-speech tool is sufficient.
