What is the primary function of Watson Speech to Text?

The primary function of Watson Speech to Text is to convert audio voice into written text. This capability allows users to transcribe spoken language into a textual format, making it a powerful tool for applications such as transcription services, voice recognition in applications, and accessibility for hearing-impaired individuals. By accurately interpreting and transcribing spoken words, Watson Speech to Text facilitates the seamless integration of voice data into text-based systems, allowing for better processing, analysis, and searchability of spoken content.

The other choices involve functionalities that do not align with the specific purpose of Watson Speech to Text. For instance, converting written text into spoken audio refers to text-to-speech technologies, while translating spoken language involves distinct processes and tools designed for language translation. Enhancing audio quality touches on audio processing, which is separate from the transcription task that is the core functionality of Watson Speech to Text.
