Using CMUPhinx to convert speech to text

Audio processed by CMUSphinx must be in Pulse Code Modulation (PCM) format. PCM is a technique that samples analog data, such as an analog wave representing speech, and produces a digital version of the signal. FFmpeg (https://ffmpeg.org/) is a free tool that can convert between audio formats if needed.

You will need to create sample audio files using the PCM format. These files should be fairly short and can contain numbers or words. It is recommended that you run the examples with different files to see how well the speech recognition works.

First, we set up the basic framework for the conversion by creating a try-catch block to handle exceptions. First, create an instance of the Configuration class. ...
