Google Docs uses speech recognition technology to transcribe audio files through a feature called Voice Typing. To access this feature, users can go to the Tools menu and select Voice typing, which will cause a microphone icon to appear on the left side of the screen. Alternatively, users can use the shortcut Control Shift S for Windows or Command Shift S for Mac to access the tool.
Once Voice Typing is activated, users can speak or play an audio file near their computer, and Google Docs will transcribe the spoken words into text in real-time. The feature supports a wide range of languages and offers voice commands for adding punctuation and formatting. Before transcribing audio from a video file, users must extract the audio data from the video file and store it in a Cloud Storage bucket or convert it to base64encoding. Google Docs uses its own speech-to-text tool to transcribe the audio, which utilizes machine learning algorithms to improve accuracy over time. Overall, Google Docs provides a convenient and efficient way to transcribe audio files using speech recognition technology.
