## TurnDetector
End-of-turn detector; decides when the caller has finished speaking.
Selected by `model`: `'echo-large'` (the default) or `'echo-small'`.
### Constructor
```typescript theme={null}
new TurnDetector(opts: TurnDetectorOptions)
```
Which detector to use: `'echo-large'` (the default) or `'echo-small'`. See TurnDetectorModel.
End-of-turn probability cutoff in \[0, 1]. Default `0.7`.
Inference service address. Falls back to the `ZRT_INFERENCE_GATEWAY` env var, then the default endpoint.
Inference service auth token. Default `''`.
Inference service base URL. Default `null`.
### cleanup
```typescript theme={null}
cleanup(): Promise
```
Tear down provider state.
### close
```typescript theme={null}
close(): Promise
```
Release any resources held by the provider.
### closeEmitter
```typescript theme={null}
closeEmitter(): Promise
```
Close the emitter: drop all handlers and stop emitting. Waits up to 2 seconds
for in-flight async handlers to settle before returning.
### detectEndOfUtterance
```typescript theme={null}
detectEndOfUtterance(chatContext?: any, threshold?: number): boolean
```
Whether the current EOU probability meets `threshold` (or the configured one).
### emit
```typescript theme={null}
emit(event: string, ...args: any[]): void
```
### getEouProbability
```typescript theme={null}
getEouProbability(_chatContext?: any): number
```
Latest end-of-utterance probability 0-1 (defaults to `0.5` when unknown).
### getRuntimeConfig
```typescript theme={null}
getRuntimeConfig(): Record
```
### listenerCount
```typescript theme={null}
listenerCount(event: string): number
```
### off
```typescript theme={null}
off(event: string, handler: EventHandler): void
```
### on
```typescript theme={null}
on(event: string, handler: EventHandler): EventHandler
```
### once
```typescript theme={null}
once(event: string, handler: EventHandler): EventHandler
```
### removeAllListeners
```typescript theme={null}
removeAllListeners(event?: string): void
```
### setThreshold
```typescript theme={null}
setThreshold(threshold: number): void
```
Update the end-of-utterance threshold.
