Audio capability in Android systems Ability to convert text to speech

In  Android systems, it is possible to control and manage audio and the ability to convert audio to text, and these features and capabilities of Android systems can be used. For example, to control and manage the voice or change the call in Android systems, you must use the AndroidManager group provided by Android. Or you can even create a program that can be used to convert audio to text. Therefore, it is possible to  listen on Android. In this section, we want to use these capabilities of Android systems. If you also want to learn, it is recommended that you follow this article.

1- To use the AndroidManager group to adjust the audio, you should do the following.

2- We can also use  setRingerMode  to adjust the voice and image of the caller. Like the following:

- RINGER_MODE_VIBRATE method:

If we use this method, the result is to put the device in vibration mode.

- RINGER_MODE_NORMAL method:

If we use this method, the result will be to put the device in a soft and noisy state.

- RINGER_MODE_SILENT method:

If we use this method, the result is to put the device in silent mode.

3- After specifying the sound mode, we need to call the  getRingerMode () method. Like the following:

- AdjustVolume method (int direction, int flags):

This method can be used to adjust the widely used sound.

- GetMode () method:

This method can be used to return the latest method.

- GetStreamMaxVolume (int streamType) method:

This method can be used to return the loudest voice indicator.

- GetStreamVolume (int streamType) method:

GetStreamVolume (int streamType) method  can be used to return the latest sound index.

- isMusicActive () method:

This method is also used to check the activeness of the melody in the system.

- StartBluetoothSco () method:

StartBluetoothSco () method  also starts the Bluetooth connection sound.

- StopBluetoothSco () method:

This method also stops the Bluetooth connection sound.

1- I use Eclipse IDE to create an Android application.

2- Name it  AudioManager  in the package com.example.audiomanager.

3- Modify the src / MainActivity.java file to add a different code.

4- The res/layout / activity_main file must be modified to add the XML component.

5- Change AndroidManifest.xml to get permissions.

6- All contents and codes that are completely included in the file and program are as follows:

He re is the content of activity_main.xml

7- The content of the activity_main.xml file is as follows:

8- The content of the  Strings.xml  file is as follows:

9- The content of the   AndroidManifest.xml file  is as follows:

10- Run the  Androidmanager application.

11- You must connect your mobile device to the computer beforehand.

12- To be able to run the program from Eclipse, we must open one of the program activity files and click Run on it.

13- Then, we are faced with a window that it is better to choose our mobile device.  14- Then select the ring and press the Current Mode button.  15- Then select Silent and press the Current Mode button.

16- Then select vibrate and press the Current Mode button.

Convert text to audio

1- To be able to convert sound to text in Android systems, we must first use the  setLanguage method. This method creates an object that can be used to determine its location. Like the following:

By entering the above code, the language of the place is specified and set.

1- America

2- Canada - France

3-Germany

4- Italy

5- Japan

6- China

2- Then, we must call speak from the group and speak the text to become a written text. Like the following:

3- We use  Eclipse IDE  to create an Android application.

4- Name it TextToSpeech in the package com.example.texttospeech.

5- Modify the src / MainActivity.java file to add a different code.

6- The res/layout / activity_main file must be changed to add the XML component.

7- Change AndroidManifest.xml to get permissions.

8- All the contents and codes that are completely included in the file and program are as follows:

7- The contents of the activity_main.xml file are as follows:

9- The contents of the Strings.xml file are as follows:

9- The contents of the Strings.xml file are as follows:

10- Contents and codes inserted in the AndroidManifest.xml file:

11- Run the TextToSpeech program.

12- You must connect your mobile device to the computer beforehand.

13- Now, we must write a text and press the Text to Speech button to convert the written text to audio.
