Explanation:

1. Dependencies:

   • Import the Google Cloud Text-to-Speech client library: com.google.cloud.texttospeech.v1

2. Setup:

   • Replace "your-project-id" with your Google Cloud Project ID.
   • Specify the fileLocation of your Telugu text file.
   • Adjust the speed value (1.0 is normal, higher values increase speed).

3. Read Text File:

   • The readFile function reads the Telugu text from the specified file.

4. Google Cloud Text-to-Speech Client:

   • The code uses the TextToSpeechClient to interact with the Google Cloud Text-to-Speech API.

5. Synthesis Input:

   • Sets the input text.

6. Voice Selection:

   • VoiceSelectionParams specifies the voice parameters.
     • LanguageCode.TELUGU: Specifies the language as Telugu.
     • You can choose from various voice names. Look at the Google Cloud Text-to-Speech API documentation for available voices.
     • SsmlGender.FEMALE: Sets the voice gender.

7. Audio Config:

   • AudioConfig defines the audio output settings.
     • AudioEncoding.MP3: Specifies MP3 as the output format.
     • setSpeakingRate(speed): Sets the speed of the speech.

8. Request and Synthesis:

   • The code creates a SynthesizeSpeechRequest and sends it to the Text-to-Speech API.
   • The API response includes the audio data in MP3 format.

9. Write Audio File:

   • The audio data is written to an output file named "output.mp3".

Remember to:

• Set up the necessary Google Cloud project and enable the Text-to-Speech API.
• Have the Google Cloud Text-to-Speech client library dependency in your project.
• Replace the placeholders with your actual values.

Additional Notes:

• You can experiment with different voice names and other voice parameters to get desired results.
• Google Cloud Text-to-Speech supports various languages, so you can easily adapt this code for other languages.
