Support challenges persist despite audio technology advancements
Google Cloud Speech-to-Text is not entirely accurate, so we have to correct for those errors in our AI software. It uses neural networks, and that stochastic processing is 70% to 75% accurate. It gets it wrong too often, and since I personally work with this, I don't appreciate that. However, they seem to be the best option currently. We have to write our own improvements because their tools to improve transcription accuracy in our domain aren't very powerful. The timestamp technology for recognized words is inadequate, so we don't use it. We understand words based on their meaning, and we have a whole AI engine that does that, which is one of our differentiators from a product standpoint. We didn't use the custom voice creation feature; we just use their voices, which are fine for our purposes.

Offers ease of use and the availability of documentation is great
The simplicity impressed me the most. We just needed a single API key. The documentation was also great. I developed the AI application using Unity, a game engine that uses C#. Then, I searched online for instructions on how to use it. I found Microsoft's GitHub repository, which provided the necessary code for integrating the Speech Service into Unity with C#. The ease of use and the availability of documentation made the process smooth and impressed me the most. The documentation and boilerplate code [a template of code] was available, which I incorporated into my application with modifications. Initially, the code functioned so that when a button was clicked, the microphone would activate and recognize my speech. One of the benefits was the ability to see my spoken words visually on the screen as I spoke. For example, if I said "I am Abhishek Rana," I could see the sentence appear in real-time. When I stopped speaking, it automatically recognized the silence and ceased, sending the text for further processing. So, the real-time translation feature has helped me a lot.
