- Introduced Volcengine as a new provider for both TTS and ASR services. - Updated configuration files to include Volcengine-specific parameters such as app_id, resource_id, and uid. - Enhanced the ASR service to support streaming mode with Volcengine's API. - Modified existing tests to validate the integration of Volcengine services. - Updated documentation to reflect the addition of Volcengine as a supported provider for TTS and ASR. - Refactored service factory to accommodate Volcengine alongside existing providers.
