Title:
AUDIO SIGNAL PROCESSING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/169021
Kind Code:
A1
Abstract:
The present invention provides an audio signal processing method and apparatus, and solves the problem that the erroneous detection occurrence probability of a Dual-Tone Multi-Frequency (DTMF) signal is high and the user satisfaction is low. The present application includes: receiving an audio signal sent down by a user; judging whether the audio signal includes a voice signal; if so, closing DTMF signal detection, or adjusting the DTMF signal detection parameter threshold so that parameter values corresponding to the audio signal fall outside the scope defined by the adjusted DTMF signal detection parameter threshold. It is obvious that the present application solves the problem that the erroneous detection occurrence probability of the DTMF signal is high and the user satisfaction is low, through directly closing DTMF signal detection or adjusting the DTMF signal detection parameter threshold.
