In Azure AI, what does the Speech service NOT provide?

The Speech service in Azure AI is specifically designed to handle various aspects of spoken language, primarily focusing on converting spoken language to text and vice versa. It offers functionalities such as text-to-speech, which allows applications to synthesize natural-sounding speech from text. Additionally, it includes speech-to-text capabilities that transcribe spoken language into written text and supports speech translation, enabling real-time translation of spoken language into different languages.

Conversely, sentiment analysis involves understanding and interpreting the emotional tone behind a body of text, which is a function typically associated with natural language processing (NLP) rather than speech recognition. While NLP and the analysis of text can include sentiment analysis, it falls outside the specific purview of what the Speech service offers. Thus, sentiment analysis is not a feature provided by Azure's Speech service, making it the correct choice in identifying what the service does not provide.
