Spoken language identification
A hotline run by Brookvale Council receives calls in English, Polish and Urdu. Before transcribing each call, the system must determine which of these languages is being spoken. Which Azure Speech feature should it use?
- A.Opinion mining
- B.Custom neural voice
- C.Key phrase extraction
- D.Language identification
Show answer and explanation
Correct answer: D. Language identification
Why: Language identification compares spoken audio with a list of candidate languages to determine which one is being spoken, and it can be combined with speech-to-text or speech translation. A custom neural voice is for synthesis, and key phrase extraction and opinion mining analyze text rather than identifying the language of audio.
