How Wake Words Work
Wake words, sometimes dubbed “hotwords” are not created equal, and this is important because a wake word can be considered the key to the front door. When the wake word is uttered, the door should open every time, in other words the rate of false rejects is ideally close to zero. When the wake word is NOT said the door shouldn’t open, or the rate of false accepts should also be close to zero. Achieving this balance of low false accepts and false rejects in an embedded algorithm for a multitude of applications requires well trained and fine-tuned AI, and with over 25 years of experience, Sensory can deliver.
Highly accurate hotword detection is made complex by factors like noise, distance, and variations in accents and language. Platforms such as Amazon, Google, and a few others seem to have pretty good wake words, but if you go into your Alexa settings you can see all of the voice data that’s been collected, and a lot of it is being collected when you weren’t intentionally talking to Alexa! You can see this performance issue in the Vocalize test report. Sensory substantially outperformed Amazon in the false reject area. There’s a reason that companies like Amazon, Google, Microsoft and Samsung have turned to Sensory for our TrulyHandsfree technology.
