Your company plans to develop a mobile app to provide meeting transcripts by using speech-to-text. Audio from the meetings will be streamed to provide real-time transcription.
You need to recommend which task each meeting participant must perform to ensure that the transcripts of the meetings can identify all participants.
Which task should you recommend?

A. Record the meeting as an MP4.
B. Create a voice signature.
C. Sign up for Azure Speech Services.
D. Sign up as a guest in Azure Active Directory (Azure AD)

Show Suggested Answer

Suggested Answer: B 🗳️
The first step is to create voice signatures for the conversation participants. Creating voice signatures is required for efficient speaker identification.
Note: In addition to the standard baseline model used by the Speech Services, you can customize models to your needs with available data, to overcome speech recognition barriers such as speaking style, vocabulary and background noise.

"The first step is to create voice signatures for the conversation participants so that they can be identified as unique speakers. The input .wav audio file for creating voice signatures should be 16-bit, 16 kHz sample rate, and single channel (mono) format...." link: https://docs.microsoft.com/bs-latn-ba/azure/cognitive-services/speech-service/how-to-use-conversation-transcription?pivots=programming-language-javascript

Wrong IMO. This is what I could infer: The prerequisite (mentioned in the article too) is to "Sign up for Speech Services". To use the REST API to create a Voice Signature, you need to sign up first. https://docs.microsoft.com/bs-latn-ba/azure/cognitive-services/speech-service/how-to-use-conversation-transcription?pivots=programming-language-javascript#prerequisites

I may be wrong. Retracting. The questions says, "You need to recommend which task EACH MEETING PARTICIPANT must perform", and not what YOU would do. YOU would sign up for Speech Services. But wouldn't recommend each participant to sign up. Each participant would Create a Voice Signature. Given answer is correct.
