DRAG DROP You need to develop an automated call handling system that can respond to callers in their own language. The system will support only French and English. Which Azure Cognitive Services service should you use to meet each requirement? To answer, drag the appropriate services to the correct requirements. Each service may be used once, more than once, or not at all. You may need to drag the split bat between panes or scroll to view content. NOTE: Each correct selection is worth one point.

1. Detect the incoming language: Speech to Text The input for this requirement is a live audio stream (a phone call). To process this, you must use the Speech to Text service, which specifically includes a Language Identification feature. This capability analyzes the audio input to determine the spoken language (e.g., distinguishing between French and English) before or during transcription. Services like Text Analytics or Translator require text input, making them unsuitable for the initial detection from raw audio.

2. Respond in the callers' own language: Text to Speech "Responding" in a call handling context implies generating an audible voice reply. The Text to Speech service is designed to convert the system's text-based responses into synthesized, human-like spoken audio in the specific target language identified (French or English).

Relevance: Confirms that the Speech service provides "Language identification" to "identify languages spoken in audio" and "Text to speech" to "convert input text into human-like synthesized speech."

Relevance: Details how "Speech to text recognition" is used when you need to "identify the language in an audio source."

Relevance: Validates that Text to speech enables applications to convert text into synthesized speech, supporting the requirement to "respond" vocally.
