A media company wants to automatically generate closed captions for its vast library of video content. The solution must provide highly accurate transcriptions, differentiate between multiple speakers, and allow for custom vocabulary specific to their industry (e.g., proper nouns of shows, character names). Which Azure AI service and feature combination is best suited for this task?
- AAzure AI Speech with speaker diarization and custom speech models
- BAzure Bot Service with QnA Maker
- CAzure Translator with document translation
- DAzure AI Language with Text Summarization
Show answer & explanationAnswer & explanation
Correct answer: A. Azure AI Speech with speaker diarization and custom speech models
Azure AI Speech is designed for speech-to-text conversion, which is essential for closed captions. Speaker diarization allows for identifying different speakers, and custom speech models enable incorporating domain-specific vocabulary to improve transcription accuracy for industry-specific terms.
Why the other options are wrong
- B. Azure Bot Service and QnA Maker are for building conversational bots and knowledge bases, not for transcribing video audio.
- C. Azure Translator is for language translation, not transcribing audio to text.
- D. Azure AI Language is for text analysis, not speech-to-text conversion.
