 Integrating external TTS/STT APIs with watsonx Orchestrate without ADK

Hi IBM Community,

I'm working with watsonx Orchestrate and I have access to third-party Text-to-Speech (TTS) and Speech-to-Text (STT) APIs from external partners. I’ve seen that the voice configuration documentation focuses on Watson TTS/STT and requires the Agent Development Kit (ADK) or Developer Edition for custom voice settings.

My question is: Is there a supported way to integrate external TTS/STT services directly into the standard watsonx Orchestrate platform (not using ADK or Developer Edition)? If not, is there a roadmap or workaround for enabling voice input/output using external providers within the standard Orchestrate environment?

Thanks in advance for any insights or examples!
