You are using the Azure Speech SDK to develop a Python application that supports real-time spoken conversations. Which Azure speech class should you…

In the Azure Speech SDK (Python), you establish and configure the connection to the Azure Speech service with the SpeechConfig class (e.g., SpeechConfig.fromsubscription or fromendpoint). AudioConfig only specifies the audio source/ sink, SpeechSynthesizer performs text-to-speech once a SpeechConfig is created, and AuditOutputConfig controls audit‐log output. None of the listed options configures the network connection or authentication parameters; therefore no listed choice is correct.

A. AudioConfig – manages microphone, stream, or file I/O; contains no keys, region, or endpoint settings.

B. SpeechSynthesizer – consumes an existing SpeechConfig to synthesize speech; does not hold connection settings itself.

C. AuditOutputConfig – directs where audit logs are stored; unrelated to service connection or authentication.
