The right way to give voice command to your cellphone out of your {custom} Android App to carry out sure operations?

This video exhibits the steps to create a voice enter or Audio recorder App utilizing Speech Recognizer API in Android. This idea can be utilized to design your {custom} App in such a method that it takes voice command as an enter to carry out sure operations akin to opening a file, beginning one other App like WhatsApp or calling a cellphone quantity or sending an SMS.

On this App it creates an ACTION_RECOGNIZE_SPEECH intent used to pay attention on a SpeechRecognizer API. It creates a easy Structure with a textView to point out the phrases spoken and begin/ cease button to start out and cease listening the SpeechRecognizer. The testing of this App could not be proven within the Emulator because the enter supply(microphone) of the Emulator typically does not works with the Laptop computer. So, the testing throughout this video was completed on an actual cellphone related to the laptop computer by way of USB cable.

The screenshots of the check outcomes together with the entire supply code with will be discovered within the beneath webpage:
