Hi Ananth Hegde (anahegde),

Greetings & Welcome to Microsoft Q&A forum! Thanks for posting your query!
I understand your query about the difference between 'speak-text-async' and 'speak_async.

Differences between speak_text_async and speak_async in the SpeechSynthesizer class:
speak_text_async:

Purpose: This method is designed specifically for synthesizing speech from plain text strings asynchronously.

Input: Accepts a single text string as input.

Use Case: Ideal for straightforward scenarios where only plain text needs to be converted into speech.

speak_async:

• Purpose: This method provides greater flexibility, allowing you to synthesize speech from a SpeechSynthesisRequest asynchronously.
• Input: Accepts a SpeechSynthesisRequest, which can include additional configuration, such as plain text, SSML (Speech Synthesis Markup Language), or other custom inputs.
• Use Case: Suitable for advanced scenarios that require more control over the input, such as using SSML for fine-tuned speech output.

The speak_async method is not available in the Java SDK for Azure Speech at this time.

Hope this helps. Do let us know if you have any further queries.
