New: Call Metrics & Artifact Improvements

You can now access detailed call performance metrics and structured output IDs directly from your call artifacts.

Turn Latencies

Each conversation turn’s latency
Call.artifact.performanceMetrics.turnLatencies

Model Latency (avg)

Average time for the model to generate a response
Call.artifact.performanceMetrics.modelLatencyAverage

Voice Latency (avg)

Average time to synthesize voice
Call.artifact.performanceMetrics.voiceLatencyAverage

Transcriber Latency (avg)

Average time to transcribe voice
Call.artifact.performanceMetrics.transcriberLatencyAverage

Endpointing Latency (avg)

Time to detect end of a conversation turn
Call.artifact.performanceMetrics.endpointingLatencyAverage

Turn Latency (avg)

Average latency to complete a conversation turn
Call.artifact.performanceMetrics.turnLatencyAverage

Structured Output IDs & Results

Track and extract structured outputs from your calls

During call: Access array of output IDs
Call.artifactPlan.structuredOutputIds
After call: Extracted outputs are stored here
Call.artifact.structuredOutputs

These improvements help you monitor, debug, and analyze your calls with greater detail.
