You are a machine learning specialist working for the digital banking division of a global banking firm. Your bank is in the process of introducing a conversational user interface for its digital banking service. The service will receive streaming audio from the conversational user interface and converse with the user in real-time. Your machine learning team lead has decided to use the Amazon Transcribe service to convert the streaming audio to streaming text.
To handle issues in the network connection when users are on mobile phones, how can you leverage the features of Amazon Transcribe to keep your solution as cost-effective as possible?

Answer options:

A.Use the Transcribe JSON streaming client.
B.Use the Transcribe HTTP/2 streaming client.
C.Use the Transcribe WebSocket protocol.
D.Use the Transcribe HTTP streaming client.

Answer: B
Option A is incorrect. The streaming client available with Transcribe is an HTTP/2 streaming client.
Option B is CORRECT. You can use the Transcribe HTTP/2 streaming client to handle retrying the connection when there are intermittent problems on the network.
Option C is incorrect. The Transcribe WebSocket protocol does not provide retry logic to handle retrying the connection when there are intermittent problems on the network. With this option, you would have to code the retry logic yourself.
