'DeepgramSTTService' object has no attribute 'sample_rate'

[agilebean]

Problem Root Cause

1. sample_rate is passed from DeepgramSTTService(STTService) to the parent class (STTService) in the init method
2. DeepgramSTTService's start method tries to access sample rate:

async def start(self, frame: StartFrame):
    await super().start(frame)
    self._settings["sample_rate"] = self.sample_rate  # <-- THIS IS THE ISSUE
    await self._connect()

3. STTService class in ai_services.py did not initialize a sample_rate attribute in its init method -> throws error 'DeepgramSTTService' object has no attribute 'sample_rate'

Suggested Solution

In STTService, initialize sample rate analog to the TTSService class:
self._sample_rate: int = sample_rate

[aconchillo]

DeepgramSTTService inherits from STTService which has a sample_rate property. See
