Abstract
Introduced here are systems and methods to increase accuracy of speech recognition by utilizing multiple sensors placed at multiple speech transmission regions such as a user's lips, throat, ear canal, etc. The various speech transmission regions are better at transmitting certain phonemes, and a sensor placed close to a particular speech transition region can more accurately detect the phoneme transmitted through the particular speech transmission region. For example, a microphone placed close to the lips can better detect labial phonemes such as m, n, p, and b, than a microphone placed close to the throat. Further, disclosed here are ways to reduce energy consumption while performing speech recognition.
