Disclosed herein is a computer-implemented method for punctuation of text from audio. The method includes obtaining an audio input comprising speech data; identifying a plurality of silent sections in the audio input; grouping the plurality of silent sections into a plurality of groups, where each group in the plurality of groups corresponds to a punctuation mark or a space without a punctuation mark; and associating each silent section in the plurality of silent sections with a punctuation mark or a space according to the grouping of the silent sections, thus obtaining punctuation information.

Computer-implemented method for punctuation of text from audio input

A computer implemented method for speech recognition from an audio signal includes: obtaining initial values for silence detection parameters including: a lead period; a threshold amplitude; and a terminal period. Detect an amplitude of the audio signal at a first time Tof the audio signal. Optionally adjusting the threshold amplitude based on the detected amplitude. Starting the speech recognition from a second time Tof the audio signal. Starting silence detection from the audio signal when the lead period has elapsed after the second time Tincluding: responsive to detecting an amplitude below the threshold amplitude for a duration of the terminal period, terminating the speech recognition and the silence detection at a third time Tof the audio signal and adjusting the silence detection parameters based on the detected amplitude changes of the audio signal between the first time Tand the third time T
