Keyword spotting
Voice commands get lost in the noise.
Your product has to hear a short command over a busy room. We clean the voice with AI speech denoising before keyword spotting, and help you build it in.

How it works
From a noisy order to a recognised command
A café is loud and keywords are short. Denoising cleans the voice first, so keyword spotting hears the words, not the room.
Your system: Sound
A spoken command in a busy room.
Your system: Microphone
The microphone in your product.
Our solution: Speech denoising
Removes the noise around the voice.
Our solution: Keyword spotting
Recognises the words you choose.
Your system: Coffee machine

What it handles
Commands, not chatter
We tune it to your words and your setting, then check each detection against what was really said in the recording.
What it catches
- Your keywords
- The words your product needs, such as drink names.
- Different voices
- High and low, fast and slow.
- Short commands
- A single word, said once.
- Busy moments
- Commands spoken over a full room.
- Your microphone
- The microphone in your product.
What it ignores
- Silence

- Other words
- Speech that isn't one of your keywords.
- Machine noise
- Grinders and fans.
- Steam
- Milk frothing and steam wands.
