About Hume AI

What is Hume AI?

A voice AI developer platform. Its Octave text-to-speech engine produces expressive, emotionally aware speech, its EVI speech-to-speech interface holds real-time voice conversations that respond to tone of voice, and it supports voice cloning. Hume AI is a specialised AI tool in the Voice/Emotion category that applies machine learning to automate, enhance, or augment tasks in this domain.

Voice cloning needs explicit, written consent from the person whose voice is used, and a synthetic voice should never be presented as a real person endorsing your business, which would risk misleading conduct under Australian Consumer Law. If EVI takes calls from Australian customers, their recordings are personal information under the Privacy Act 1988, and callers should be told they are speaking with AI. Hume's CEO joined Google DeepMind under a licensing deal in early 2026, so confirm the product roadmap before committing to a long build.

Launched: 2021HQ: New York, USA

Pricing

A free tier for experimenting, then monthly plans that include a set amount of text-to-speech characters and conversation minutes, with pay-as-you-go overage. Enterprise pricing is available for high volumes. Check hume.ai/pricing for plan details.

Details checked against the vendor's website in October 2026. Pricing changes often, so confirm current plans at hume.ai.

Data Residency & Privacy in Australia

Hume does not publish an Australian hosting region or let customers choose where data is processed. Its API data usage policy says customer-submitted data is not used to train its general models, and custom model data is used only for that customer. Ask Hume where audio and transcripts are stored, how long they are kept and which sub-processors handle conversations.

Getting Started with Hume AI in Australia

Hume AI is available directly at hume.ai. Sign up for a trial or free tier to evaluate the tool for your specific use case. Identify one clear workflow to start with, measure results over 30 days, and expand from there. Reach out to the vendor's support team for onboarding guidance.

Outside help is most useful when the tool has to connect to existing systems, handle personal information, or be rolled out to a whole team. AI Lab Australia works with businesses across Sydney, Melbourne, Brisbane, Perth and Adelaide on that setup.

Frequently Asked Questions About Hume AI

Is Hume AI still operating after the Google DeepMind deal?

Yes. In January 2026 Hume's chief executive and a small group of engineers joined Google DeepMind under a non-exclusive licensing agreement, while Hume continues to operate and sell its voice APIs to other customers. Check the product roadmap and support commitments in your contract before building a long-term voice product on it.

Can I legally clone a voice with Hume AI in Australia?

You can clone a voice you have permission to use. Get written consent from the speaker covering how and where the synthetic voice will be used, and avoid voices that imitate public figures. Using a cloned voice to imply a real person endorses your business could be misleading conduct under Australian Consumer Law.

Does Hume AI have a free plan?

Yes, a free tier lets developers experiment with text-to-speech and conversational voice before paying. Paid monthly plans include larger allowances of characters and conversation minutes, with usage-based overage and enterprise pricing for heavy volumes. Check hume.ai/pricing for current allowances, which shift as new models are released.

Should callers be told they are talking to Hume's voice AI?

Yes. Tell callers early that they are speaking with an AI system and offer a way to reach a person. Call audio and transcripts are personal information under the Privacy Act 1988, so your privacy notice should cover recording, overseas processing and retention, and state surveillance devices laws may require consent to record.
