Which of the following features of Azure AI Speech needs to be used by educators for comprehensive assessments of prosody?
A. Custom neural voice
B. Pronunciation assessment
C. Prosodic unit creation
D. Closed captions
Answer
B. Pronunciation assessment
Explanation
Pronunciation assessment is specifically designed to provide feedback on various aspects of speech, including prosody. This refers to the elements of speech that influence how something is said, such as:
- Rhythm: Pattern of stressed and unstressed syllables.
- Intonation: Pitch variation of the voice.
- Stress: Emphasis placed on certain words or syllables.
- Rate: Speed of speaking.
The pronunciation assessment feature of Azure AI Speech provides feedback on accuracy, fluency, prosody, vocabulary, grammar, and topic understanding. It benefits educators by saving time on assessments and offering consistency. It also benefits students by offering convenient practice, authoritative scoring, and text order assistance. Other features of Azure AI Speech include:
Speech to text:
- Supports real-time language identification for multilingual learning scenarios.
- Enhances interpersonal interaction by improving understanding and context.
Text to speech:
- Prebuilt neural voices can read learning materials in native languages, facilitating self-directed learning.
- Supports diverse languages and voices for various applications (AI teacher, content narration, etc.).
- Offers custom neural voice creation to personalize learning experiences.
- New languages are continuously being added.
Custom neural voice is a feature that allows for creating personalized synthetic voices, but it does not directly assess the prosody of learners’ speech.
Prosodic unit creation is a speech synthesis process that groups words into phrases and sentences and is not an assessment tool for learners.
Closed captions are text transcripts of spoken content and are not applicable for assessing prosodic elements.
