Methods and systems for transcription

A system for transcription, the system comprising:

• a memory;
• one or more processors coupled to the memory, the one or more processors configured to:
• receive, from a first transcription engine, one or more transcribed portions of a media file;
• identify, by a transcription analyzer of the conductor, a first transcribed portion, from the one or more transcribed portions, with a confidence value below a predetermined threshold;
• request analysis of a first audio segment corresponding to the first transcribed portion;
• receive, in response to request for analysis, an analysis result having a revised-transcription portion of the first audio segment, wherein the revised-transcription portion comprises one or more segments of the first transcribed potion that have been revised;
• and
• replace the first transcribed portion with the revised-transcription portion.

The system of claim 11, wherein the one or more processors, after identifying the first transcribed portion and before requesting analysis on the first transcribed portion, are further configured to:

• send the first audio segment to a plurality of transcription engines;
• receive successive transcribed portions from the plurality of transcription engines;
• and
• replace the first transcribed portion with one of the received successive transcribed portions based on the second confidence value of the one of the received successive transcribed portions.

The system of claim 18, wherein the one or more processors are further configured to:

• train a machine learning model using a training data set from the low-confidence database;
• identify, by a transcription analyzer, a second transcribed portion having a third confidence value below a second predetermined threshold from the one or more transcribed portions;
• and
• using the trained machine learning model, re-transcribe a second audio segment of the media file that corresponds with the second transcribed portion.

A method for transcription, the method comprising:

• receiving one or more transcribed portions of a media file;
• determining a confidence of accuracy value for each of the one or more transcribed portions;
• identifying a first transcribed portion that has a first confidence value below a predetermined threshold;
• constructing a phoneme sequence of an audio segment corresponding to the first transcribed portion based on at least on a reward function;
• creating a new audio waveform based at least on the constructed phoneme sequence;
• generating a new transcription using a transcription engine based on the new audio waveform;
• and
• replacing the first transcribed portion with the new transcription.
