EMPHASIS OF SHORT-DURATION TRANSIENT SPEECH FEATURES |
摘要 |
<p>A sound processor including a microphone ( 1 ), a pre-amplifier ( 2 ), a bank of N parallel filters ( 3 ), means for detecting short-duration transitions in the envelope signal of each filter channel, and means for applying gain to the outputs of these filter channels in which the gain is related to a function of the second-order derivative of the slow-varying envelope signal in each filter channel, to assist in perception of low-intensity short-duration speech features in said signal.</p> |
