Speech processing system and method

A speech processing method implemented by the speech processing device, the speech processing device comprising a storage unit storing a plurality of audio files, a plurality of voice models, and personal information associated with each of voice model, the speech processing method comprising:

• extracting voice features from the stored audio files in response to user operation;
• determining whether one of the extracted speaker's voice features matches a selected voice model in response to a user operation of selecting one voice model from the stored voice models;
• extracting speech(s) of a speaker from one or more audio files that contains voice feature matching the selected voice model, to form a single audio file, implementing a speech-to-text algorithm to create a textual file generated based on the single audio file;
• and recording time point(s) when one word appears in the single audio file for each word in the textual file;
• associating each of the words in the converted text with corresponding recorded time points recorded;
• searching for an input keyword in the converted textual file in response to a user operation of inputting the keyword;
• and
• obtaining a time point associated with a word first appearing in the textual file that matches the keyword, and further controlling an audio play device to play the single audio file at the determined time point.

A storage medium storing a set of instructions, the set of instructions capable of being executed by a processor of a speech processing device, cause the speech processing device to perform a speech processing method, the method comprising:

• extracting voice features from the stored audio files in response to user operation;
• determining whether one of the extracted speaker's voice features matches a selected voice model in response to a user operation of selecting one voice model from the stored voice models;
• extracting speech(s) of a speaker from one or more audio files that contains voice feature matching the selected voice model, to form a single audio file, implementing a speech-to text algorithm to create a textual file generated based on the single audio file, and recording time point(s) each time when each of words appears in the single audio file;
• associating each of the word in the converted text with corresponding recorded time point;
• searching for an input keyword in the converted textual file in response to a user operation of inputting the keyword;
• and
• obtaining a time point associated with a word first appearing in the converted textual file that matches the keyword, and further controlling an audio play device to play the single audio file at the determined time point.
