Speech, as the most natural way we express ourselves, has tremendous potential as a method of human-machine interface. Speech recognition technologies have improved significantly but are still dependent on factors that influence the signal to "noise" ratio. During the last three years Alango, a leading provider of speech and audio enhancement DSP technologies, has accumulated significant practical experience in integration of front-end speech enhancement and speech recognition. In this presentation we will discuss all aspects of signal processing in Smart Home devices, including multi-microphone beamforming, echo cancellation, as well as keyword recognition and the computational resources necessary to perform such tasks. We'll discuss both technology and system aspects. Additionally, we will share our vision for the voice interface of the future and discuss R&D topics to make it a reality.
