Realtime Voice Support Agent
Reference solution for taking one customer voice-support session through speech capture, request interpretation, supporting knowledge retrieval, optional operational context lookup, grounded response generation, and spoken delivery.
Unit event
Customer Voice Session
CUSTOMER_VOICE_SESSIONOne customer voice-support session taken through speech capture, request interpretation, supporting knowledge retrieval, optional operational context lookup, grounded response generation, and spoken delivery.
Design variant
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.
Scenario inputs
Every value this design resolves, and who owns it. Change an editable value and the figures recalculate. The pricing engine answers, not this page: nothing here multiplies anything, and until it answers the figures beside you are the ones you were already looking at, labelled as such.
58 fields
Receive & Understand Voice6 fields
How long the customer spoke. The only quantity the input-audio meter reads, and never the same number as the assistant's speaking time.
How large the transcript is expected to be. A Scenario assumption carried forward as this Activity's output, not a conversion from duration.
Text this recognition step sends as prompt input. Zero in this solution, stated rather than omitted: an offering whose schedule also holds an unconditional text INPUT rate refuses a request that says nothing about tokens. Wave 3 review §2.

Direct unit total
0.140898 USDBars show each operation’s share of the stated direct unit total. An operation with no priced activity shows no amount, which is not an amount of zero.
Assumptions, issues and reproducibility
Activity states not exercised by this configuration
The read model reports these so their absence reads as absence rather than as coverage.
Issues
The runtime reported none for this configuration.
