That means you can get off your feet without having to sign up for a service. Before we get to the nitty-gritty of doing speech recognition in Python, let’s take a moment to talk about how speech recognition works. A full discussion would fill a book, so I won’t bore you with all of the technical details here.
The first key, "success", is a boolean that indicates whether or not the API request was successful. The second key, "error", is either None or an error message indicating that the API is unavailable or the speech was unintelligible. Finally, the "transcription" key contains the transcription of the audio recorded by the microphone. The adjust_for_ambient_noise() method reads the first second of the file stream and calibrates the recognizer to the noise level of the audio. Hence, that portion of the stream is consumed before you call record() to capture the data. What if you only want to capture a portion of the speech in a file?
Speech recognition has its roots in research done at Bell Labs in the early 1950s. Early systems were limited to a single speaker and had limited vocabularies of about a dozen words. Modern speech recognition systems have come a long way since their ancient counterparts. They can recognize speech from multiple speakers and have enormous vocabularies in numerous languages. Doctors can use speech recognition software to transcribe notes in real time into healthcare records.
Most recently, the field has benefited from advances in deep learning and big data. Some of these packages—such as wit and apiai—offer built-in features, like natural language processing for identifying a speaker’s intent, which go beyond basic speech recognition. Others, like google-cloud-speech, focus solely on speech-to-text conversion. It’s considered to be one of the most complex areas of computer science – involving linguistics, mathematics and statistics.

To turn on the screen by voice, go to the Google app Settings Voice "Ok Google" detection, then turn on Say "Ok Google" any time. The only lock screen currently supported by Voice Access is the PIN unlock. To protect your security when you enter your PIN, Voice Access shows random words on the screen (such as "red" or "blue") instead of Voice Access number labels. You can change your lock screen in Settings Security under Device security.

Since models aren’t perfect, another challenge
is to make the model match the AI-powered chatbot speech. For dictation, the recording & recognition - is delegated to and done by the browser (Chrome / Edge) or operating system (Android). So, we never even have access to the recorded audio, and Edge's / Chrome's / Android's (depending the one you use) privacy policy apply here.
