Frequently asked questions about
our voice AI
What makes SoundHound's voice AI different?

It is the only voice AI model natively tied to a foundational audio recognition model (not voice-first, but native), combining proprietary STT and LLM intent models. Backed by 200+ patents, it delivers an industry-leading (lowest) Word Error Rate and real-time voice-to-voice processing.

How does it handle interruptions and natural turn-taking?

The model understands the rhythm of human conversation, so callers can interrupt, put it on hold, or change their mind mid-sentence without breaking the interaction, thanks to dynamic turn-taking.

How does it perform in noisy, real-world environments?

Whether in a crowded kitchen or a moving car, the model finds the signal in the noise, holding up in the real-world environments where accuracy counts most.

Can it detect sentiment or emotion?

Yes. The model reads emotion and real intent, not just soundwaves, so agents can respond appropriately and surface sentiment in your analytics.

Can it switch languages mid-conversation?

Yes. The voice AI is multilingual and can switch languages on the fly within a single conversation.

Can we choose a custom brand voice or wake word?

Yes. You can choose a voice that fits your brand, and SoundHound's data collection and labeling process can deliver a custom, branded wake word in weeks, not months.

Why is a native voice model faster and more cost-efficient?

Because processing is fully native and single-step (rather than stitching together separate services), there is no added lag and usage costs are lower.
