Systems, methods, and devices for intelligent speech recognition and processing

A method for improving intelligibility of a speech signal, comprising:

• at least one processor receiving an incoming speech signal;
• the at least one processor identifying a voice fundamental frequency of the incoming speech signal;
• the at least one processor processing the incoming speech signal by analyzing the speech signal to extract the periodic pitch pulses that stimulate the resonances of the vocal tract in voiced speech, the frequency of these periodic pitch pulses being the voiced fundamental frequency;
• the at least one processor replacing the extracted periodic pitch pulses of the incoming speech signal with periodic pitch pulses that stimulate a wider frequency range of vocal tract resonances with a greater intensity;
• and
• the at least one processor outputting the processed speech signal.

A method for improving intelligibility of a speech signal, comprising:

• at least one processor receiving an audio signal comprising an incoming speech signal;
• the at least one processor recognizing an acoustic environment for the audio signal;
• the at least one processor recognizing a sound element in the received speech signal to improve the intelligibility thereof;
• the at least one processor determining a signal processing strategy for processing the sound element based on the acoustic environment;
• the at least one processor applying the determined signal processing strategy to the identified sound element;
• and
• the at least one processor outputting a processed speech signal comprising the processed sound element.
