Abstract
A method for detecting a speech rate is disclosed. The method for detecting the speech rate includes: obtaining a digital audio signal; acquiring a plurality of audio frames from the digital audio signal and setting an observation window that includes a plurality of first audio frames in the audio frames; determining whether the observation window belongs to speech or not; if the observation window belongs to speech, performing a local peak detection on the first audio frames; accumulating a syllable count if the local peak detection shows that the first audio frames include a discontinuous peak; and calculating the speech rate based on the syllable count.
Claims20
An electronic device for detecting a speech rate, comprising:
- a memory configured for storing a plurality of instructions;
- and
- a processor communicatively connected to the memory and configured for executing the plurality of instructions to complete following procedures:
- obtaining a digital audio signal;
