Design variants The same solution, implemented 2 ways. Choosing one changes the workflow and dependencies described below; it does not calculate anything.
Text-Orchestrated Voice Opens first A dedicated speech-recognition model transcribes the customer, the existing support pipeline answers in text, and a dedicated text-to-speech model speaks the answer. Native Realtime Voice One realtime audio model both recognizes the customer's speech and speaks the answer, with the same text support pipeline between them. Not a single full-duplex speech-to-speech session: §2 defers that until distinct input and output durations are proven.
How it works Expand all 6 operations and 11 activities, in the order they run. Expand an operation to see its activities.
1
Receive & Understand Voice 1 activity Capture the customer's speech and turn it into a request the support pipeline can read.
2
Interpret & Plan Support 1 activity Interpret the request and plan what the answer needs.
3
Retrieve Supporting Knowledge 5 activities Find and assemble the enterprise knowledge the answer is grounded in.
4
Execute Required Action 2 activities Look up whatever operational record the request needs and normalize it.
5
Generate Support Response 1 activity Write the grounded answer as text.
6
Deliver Spoken Response 1 activity Speak the answer back to the customer.
What this solution uses For Text-Orchestrated Voice. An activity that calls a model and a service appears in both groups.
