7-7: LGTM. Consider adding documentation for PLAYBACK_DELTA.The addition of
PLAYBACK_DELTAto the imports is correct and aligns with the PR objectives. This new constant is now available at the package level, which is good for accessibility.Consider adding a brief comment or docstring in this file or in the
constants.pyfile to explain the purpose and usage ofPLAYBACK_DELTA. This would improve code readability and make it easier for other developers to understand its role in the audio playback functionality.deepgram/audio/speaker/constants.py (1)
14-15: Please clarify the purpose and unit ofPLAYBACK_DELTA.The new constant
PLAYBACK_DELTAhas been added, but its purpose and unit are not immediately clear. To improve code readability and maintainability:
- Add a comment explaining the purpose of this constant.
- Specify the unit (e.g., milliseconds, samples) in the comment.
- Consider using a more descriptive name if applicable, e.g.,
PLAYBACK_DELAY_MSif it represents a delay in milliseconds.Example:
# Delay in milliseconds to ensure playback completion PLAYBACK_DELAY_MS = 2000examples/text-to-speech/websocket/complete/main.py (1)
101-102: Consider adding an explanatory commentThe addition of
wait_for_complete()significantly improves the script. To further enhance its educational value for users new to the Deepgram SDK, consider adding a brief comment explaining the purpose of this method. For example:# Wait for the text-to-speech processing to complete before proceeding dg_connection.wait_for_complete()This would help users understand the importance of this step in the text-to-speech process.

1-138: Well-structured script with robust error handling.The overall structure of the script is well-organized and follows good practices for asynchronous programming. The changes integrate seamlessly with the existing code. Here are some positive observations:
- Proper use of asyncio for asynchronous operations.
- Signal handlers set up for graceful shutdown.
- Comprehensive error handling with try-except blocks.
- Clear separation of concerns between different parts of the script.
One minor suggestion for improvement:
Consider adding more specific exception handling for network-related errors, as they are likely in a websocket-based application. For example:
import aiohttp try: # ... existing code ... except ValueError as e: print(f"Invalid value encountered: {e}") except aiohttp.ClientError as e: print(f"Network error occurred: {e}") except Exception as e: print(f"An unexpected error occurred: {e}")This would provide more detailed error information for debugging network-related issues.

210-211: Correct typo in the docstring ofwait_for_completemethodThe docstring contains a typo: "speak" should be "speaker".
Apply this diff to correct the typo:
""" - This method will block until the speak is done playing sound. + This method will block until the speaker is done playing sound. """
235-236: Clarify logging messages inwait_for_completemethodThe logging message
"LastPlay delta is less than threshold"may be unclear to someone reviewing logs. Consider rephrasing it for better clarity.Update the logging messages for clarity:
if diff_in_ms < delta_in_ms: - self._logger.debug("LastPlay delta is less than threshold") + self._logger.debug("Time since last audio data (%f ms) is less than threshold (%f ms). Continuing to wait.", diff_in_ms, delta_in_ms) continue ... self._logger.debug("LastPlay delta is greater than threshold. Exit wait!")Similarly, update the exit message:
self._logger.debug("LastPlay delta is greater than threshold. Exit wait!") + self._logger.debug("Time since last audio data (%f ms) exceeds threshold (%f ms). Exiting wait.", diff_in_ms, delta_in_ms)deepgram/clients/speak/v1/websocket/client.py (1)
601-602: Correct grammatical error in docstringThe docstring has a grammatical error. It should be rephrased for clarity.
Apply this diff to correct the docstring:
""" - This method will block until the speak is done playing sound. + This method will block until the speech is done playing sound. """

7-7: LGTM: Comment update reflects the new focus on speaker functionality.The change from "Constants for microphone" to "Constants for speaker" accurately represents the shift in focus and aligns with the PR objective of implementing speaker-related functionality.
deepgram/audio/__init__.py (1)
21-21: LGTM! Verify usage in Speaker class.The addition of
PLAYBACK_DELTA as OUTPUT_PLAYBACK_DELTAto the import list is consistent with the existing naming convention and aligns with the PR objective of implementingwait_for_complete()for the Speaker class.To ensure this constant is being utilized as intended, let's verify its usage in the Speaker class implementation:
✅ Verification successful
Action Required: Corrected shell scripts to verify usage of
OUTPUT_PLAYBACK_DELTA
Action Required: Locate
Speakerclass and verifyOUTPUT_PLAYBACK_DELTAusage
Verified: OUTPUT_PLAYBACK_DELTA correctly added to the public interface and not used internally.

96-96: Improved code readabilityThe addition of a blank line after sending text to Deepgram enhances code readability by clearly separating different logical blocks of the script.
101-102: Improved reliability with dynamic waitThe replacement of a fixed
time.sleep(5)withdg_connection.wait_for_complete()is a significant improvement:
- It eliminates the risk of premature script termination if text-to-speech processing takes longer than 5 seconds.
- It optimizes execution time by avoiding unnecessary waiting if processing completes faster than 5 seconds.
This change effectively demonstrates the practical application of the new
wait_for_complete()feature in the Deepgram SDK.
Line range hint
1-124: Summary of changesThe modifications to this example script effectively demonstrate the new
wait_for_complete()feature of the Deepgram SDK. These changes provide a more robust and efficient approach to handling text-to-speech completion, making the example more valuable for users learning to work with the SDK. The script now better reflects best practices for using Deepgram's text-to-speech functionality.examples/text-to-speech/websocket/async_complete/main.py (3)
105-105: Improved handling of text-to-speech completion.The changes in this section significantly improve the code:
The added blank line (105) enhances readability by clearly separating the text sending and completion waiting steps.
Replacing the previous sleep call with
await dg_connection.wait_for_complete()(110) is an excellent improvement:
- It eliminates the hard-coded wait time, making the code more flexible and efficient.
- It aligns perfectly with the PR objective of implementing the
wait_for_complete()method.- It likely provides a more accurate way to determine when the text-to-speech operation is complete.
These changes make the code more robust and easier to maintain.

1-138: Summary: Excellent implementation ofwait_for_complete()with well-integrated changes.This PR successfully implements the
wait_for_complete()method for the Speaker class, as intended. The changes in this example script effectively demonstrate the usage of the new feature and integrate well with the existing code structure. Key improvements include:
- Proper configuration setup for speaker playback.
- Replacement of the hard-coded sleep with the new
wait_for_complete()method.- Maintained overall script structure with good error handling and asynchronous programming practices.
The changes align perfectly with the PR objectives and provide a clear example for users of the Deepgram Python SDK. The script now offers a more efficient and accurate way to handle text-to-speech operations.
35-39: Configuration changes impact behavior and logging verbosity.The changes to the
DeepgramClientOptionsconfiguration have the following effects:
Commenting out
"auto_flush_speak_delta": "500"disables automatic flushing. Ensure this aligns with the intended behavior, as manual flushing is now required (which is done on line 107).Setting
"speaker_playback": "true"enables speaker playback, which is consistent with the PR objective of implementingwait_for_complete().Changing
verbosetoverboselogs.SPAMsignificantly increases logging verbosity. While this is useful for debugging, consider using a less verbose level in production to avoid performance impacts.To ensure these changes are consistent across the codebase, run the following script:
✅ Verification successful
Configuration changes are consistently applied and verified across the codebase.
The adjustments to the
DeepgramClientOptionsinexamples/text-to-speech/websocket/async_complete/main.pyare consistent and do not introduce any inconsistencies in other parts of the codebase. The commented-out configurations in other files indicate deprecated or inactive settings, ensuring that only the intended examples are affected by the changes.🏁 Scripts executed
