Configuration Reference

`InitParams` — passed to `Initialize()`

Field	Type	Description
`apiKey`	string	Developer Console API key (required).
`secureMedia`	bool	Encrypt media with SRTP. Default: `false`.
`logPath`	string	Directory for SDK log files. Default: `"."` (working directory).
`jitterParams`	`optional<JitterParams>`	Global jitter-buffer settings (see below).

`AudioParams` factory methods

// Language Translation
AudioParams::WithLanguages(
    langIn,          // source language (BCP-47) or "*" for auto-detect
    langOut,         // target language (BCP-47)
    sampleRate,      // 8000 / 16000 / 48000
    conversationId   // optional — auto-generated if empty
);

// Speech Enhancement / Accent Translation
AudioParams::WithModel(
    modelKey,        // model identifier from Developer Console
    sampleRate       // 8000 / 16000 / 48000
);

`LanguageConfig` — for `UpdateLanguageConfig()`

Field	Type	Description
`languageIn`	string	Source language BCP-47 code. `"*"` = auto-detect.
`languageOut`	string	Target language BCP-47 code.
`conversationId`	string	Must match the ID used at processor creation.

`JitterParams` — advanced network tuning

The adaptive jitter buffer smooths network jitter at the cost of added latency. All fields default to −1 (use the service default). Only adjust if you have a measured need.

Field	Service default	Description
`jbMaxMs`	500 ms	Maximum buffer capacity.
`jbInitPrefetchMs`	300 ms	Initial prefetch delay before playback starts.
`jbMinPrefetchMs`	300 ms	Adaptive floor for the jitter buffer.
`jbMaxPrefetchMs`	400 ms	Adaptive ceiling for the jitter buffer.

Higher prefetch values improve resilience to jitter but add latency. Start with the defaults and increase only if you observe choppy audio.
