Enhanced transcription of audio data with punctuation markings based on silence durations

A system comprising:

• a data store storing specific computer-executable instructions;
• and
• a computing device in communication with the data store, the computing device including a processor that executes the specific computer-executable instructions to cause the system to at least:
• receive an audio file including audio data for spoken words;
• transmit, to a transcription device, the audio file;
• receive, from the transcription device, transcription information, wherein the transcription information includes:
• (i) a transcript of the spoken words, and
• (ii) word timings identifying a position where the transcription device identified each of the spoken words in the audio data;
• detect an audio silence in the audio data;
• associate the audio silence with a word timing for a spoken word included in the spoken words based on a matching of a start time of the audio silence with an end time of the spoken word, wherein the start time of the audio silence is determined from the audio data, and wherein the end time of the spoken word is included in the word timings received from the transcription device;
• remove punctuation characters from the transcript of the spoken words;
• and
• generate a punctuated transcript by including a punctuation mark adjacent to the spoken word associated with the audio silence.

A computer-implemented method comprising:

• under control of one or more processing devices,
• receiving an audio file including audio data for spoken words;
• transmitting, to a transcription device, the audio file;
• receiving, from the transcription device, transcription information, wherein the transcription information includes:
• (i) a transcript of the spoken words, and
• (ii) word timings identifying a position where the transcription device identified each of the spoken words in the audio data;
• detecting a non-speech portion of the audio data based at least in part on at least one of:
• amplitude, frequency, pitch, speed, or tone of the non-speech portion of audio data in relation to a non-speech detection threshold;
• associating the non-speech portion with a word timing for a spoken word included in the spoken words based on a matching of a start time of the non-speech portion with an end time of the spoken word, wherein the start time of the non-speech portion is determined from the audio data, and wherein the end time of the spoken word is included in the word timings received from the transcription device;
• removing punctuation characters from the transcript of the spoken words;
• and
• generating a punctuated transcript by including a punctuation mark adjacent to the spoken word associated with the non-speech portion.
