Get agent

Description of all the tools you'd like to add to the agent. It needs to be a JSON string as this will be passed to LLM.

Parameters for each tool, where keys must match the `name` field in the `tools` array.

Bodhi

Ambient noise

Track for ambient noise can be coffee-shop, call-center, office-ambience

Track for ambient noise

This will enable agent to acknowledge when user is speaking long sentences

Backchanneling

Gap between every successive acknowledgement. We will also add a random jitter to this value to make it more random

Backchanneling Message Gap

Basic delay after which we should start with backchanneling

Backchanneling Start Delay

Call Cancellation Prompt

The call automatically disconnects reaching this limit

Terminate a call after specified number of seconds

Weather to use LLM prompt to hang up or not. Pretty soon this will be replaced by predefined function

Hangup After Llmcall

Time to wait in seconds before hanging up in case user doesn't speak a thing

Hangup After Silence

Since we work with interim results, this will dictate the linear delay to add before speaking everytime we get a partial transcript from ASR

Incremental Delay

To avoid accidental interruption, how many words should we wait for before interrupting

Number Of Words For Interruption
