Code Review Summary

Change Overview: The primary aim of these changes is to make the speech model configurable by introducing a new setting in the application's configuration files. This allows for dynamic configuration of the SpeechModel used by the application, making it more flexible and adaptable to different contexts and use cases.

Issue 1: Configuration Management

• Description: The SpeechModel property is set to a default value of "googlev2_telephony" in the application's settings. While having a default is useful, this could lead to mismatches if the intended model is different.
• Suggestion: Consider loading the default value from a configuration file or environment variable. This would make it easier to manage different environments (e.g., development, testing, production) without changing the code.
• Example:

  // Before
  public class TwilioSetting
  {
      public string SpeechModel { get; set; } = "googlev2_telephony";
  }
  
  // After
  public class TwilioSetting
  {
      public string SpeechModel { get; set; } = Configuration.GetValue<string>("DefaultSpeechModel", "googlev2_telephony");
  }
