# AudioFillerSettings
<a name="API_AudioFillerSettings"></a>

Configuration that plays background filler audio during speech-to-speech interactions to mask processing delays and improve the perceived responsiveness of the bot.

Audio filler requires `unifiedSpeechSettings` (speech-to-speech) to be enabled on the bot locale when `enabled` is `true`.
