What is the primary function of Azure AI speech?

The primary function of Azure AI speech is to convert spoken words into text and vice versa, enabling features such as voice commands and dictation. This capability is fundamental in creating seamless interactions between users and applications, allowing for more natural communication methods. By leveraging automatic speech recognition (ASR) technology, Azure AI speech can accurately transcribe spoken language into text, facilitating various applications including voice-activated services, transcription of meetings, and even the voice input for text messaging.

Additionally, the text-to-speech (TTS) functionality allows applications to convert text back into spoken words, enabling scenarios like reading text aloud in applications or creating voice responses in customer service bots. These two core functionalities of converting speech to text and generating speech from text are essential for enhancing user experience and accessibility.

The other options focus on different functionalities that are not the primary purpose of Azure AI speech. Analyzing customer demographics pertains more to data analytics rather than speech technology, generating textual reports is a function associated with document processing or data analysis tools, and sentiment analysis is typically performed on textual data rather than spoken language.
