Converting speech or audio to text has a large number of applications and can bring advanced capabilities to applications.
Image you are running a call center with thousands of simultaneous calls. You would like to identify some trends/analytics such as if the callers are having problems with a particular product or feature. Or if the callers sound frustrated or unhappy about something.
You might also be looking for particular words in the conversation that are being repeated and also need to know the frequency. Being able to analyze such information is vital to businesses. For example, if you identified that callers sound frustrated and the word “broken” is repeated all the time – you can take actions to improve the user experience. First, you can quickly teach the support team how to help with this particular problem, offer a solution or a workaround. Second, you can fix or improve the product.
In general, almost any audio can be converted to text, where the text is then analyzed for trends, analytics that are important to you. One tool that you can use to analyze text is the Watson Tone Analyzer service.
