Bad application data: Google’s voice search is a part of its main application which is installed on your smartphone.If someone else is trying to do a voice search, the module will not respond and will stay idle. Different people: Google is set to respond to a specific set of people’s voice of ‘Ok Google’.The voice recognition module being out of sync is a common issue and re-training it usually solves the problem.
Voice recognition is an issue and requires a lot of Artificial Intelligence so Google trains your model again and again.
Training issues: Google trains itself with your voice so it can recognize you properly every time. If you have a bad or limited internet connection, the search will not work at all and stop responding to you. Internet issues: Whenever you search through ‘Okay Google’, it always uses an internet connection to fetch the results. Since Google can also be counted as a personal assistant, there are chances that Bixby is interfering with Google and not letting it operate. Bixby interference: Bixby is a personal assistant operated by Samsung and is available by default in all new Samsung devices. Here you can troubleshoot your microphone and check if it is really the cause of the error. Microphone issues: If your very microphone is not working, Google will not be able to register your voice automatically and it would be as if nothing happened at all. By default, English (US) is set but it is always worth checking anyway. Wrong language settings: There is also a possibility that the language you are speaking doesn’t match with the one fed into Google. If the service is down, there is nothing you can do except wait for it to be up again.
Backend Servers Down: There are several cases where Google’s service was down itself at the backend.
