ELI5:How does voice analytic software work?

And does inflections and or accents effect the probability of matching?

Most speech to text software works based on machine learning algorithms that use statistics.

The gist of it is that you can "teach" computer software to become good at pattern matching. By analyzing the wave pattern of the sound you make when you say words, and by telling the computer what the word is for each pattern, you can train the computer software to match a sound pattern to a word.

So if you have a large amount of voice clips, and someone has transcribed all those clips, you have created something called "training data", which you can feed into the software to teach it how to match those patterns.

Accents will effect the probability of matching if the software wasn't trained with recordings of accents.  But that's easily fixable by adding accented data to the training data.
