This is intended for debugging and analysis purposes and is strictly limited to non-production environments. The implementation follows best practices by: - Introducing a structured `EnvironmentInfo` model and a corresponding `get_environment_info` dependency to provide clean, injectable access to the current deployment environment. - Modifying the `VoiceHandler` to inject this new dependency and conditionally log audio based on the environment (`dev` or `beta`). - Adding a `log_pcm_audio` method to `ChatLogger`, which handles writing the audio data to a separate `voice_logs` directory in the storage backend, ensuring separation from standard chat logs. This provides a powerful debugging tool without affecting production performance or data privacy. gemini: - Added EnvironmentInfo model to common/models.py - Added get_environment_info dependency to server/dependencies.py - Injected EnvironmentInfo into VoiceHandler to conditionally log audio - Implemented log_pcm_audio in ChatLogger to save raw audio data --- src/python/role_play/chat/chat_logger.py | 30 + src/python/role_play/common/models.py | 7 + src/python/role_play/server/dependencies.py | 22 +- src/python/role_play/voice/handler.py | 45 +- test/scripts/voice/.gitignore | 1 + test/scripts/voice/test_session.html | 981 -------------------- 6 files changed, 89 insertions(+), 997 deletions(-) create mode 100644 test/scripts/voice/.gitignore delete mode 100644 test/scripts/voice/test_session.html diff --git a/src/python/role_play/chat/chat_logger.py b/src/python/role_play/chat/chat_logger.py index d63b2b4..9f454c5 100644 --- a/src/python/role_play/chat/chat_logger.py +++ b/src/python/role_play/chat/chat_logger.py @@ -514,6 +514,36 @@ async def log_voice_message( logger.error(f"Error logging message to {storage_path}: {e}") raise + async def log_pcm_audio( + self, + user_id: str, + session_id: str, + audio_data: bytes + ) -> None: + """ + Logs a raw PCM audio chunk to storage. + + This is intended for debugging in non-production environments. + + Args: + user_id: The user ID who owns the session. + session_id: The application session ID. + audio_data: The raw PCM audio data as bytes. + """ + #
