Last updated 6 months ago

The API also offers detailed feedback on each of the Pronunciation, Fluency, Vocabulary, Grammar and Cohesion metrics. Such feedback can be used to explain why a user got a low score on a specific metric. Such feedback is available in the following nodes:

Node
Description

fluency

This node contains metrics and sub-scores for the overall utterance and for each segment (sentence) within the utterance.

word_score_list[]

This node contains scores and metrics for each word, syllable, and phoneme within the utterance.

grammar

This node contains grammar metrics, errors and feedback for the overall utterance.

vocabulary

This node contains vocabulary metrics, errors and feedback for the overall utterance.

coherence

This node contains coherence metrics, errors and feedback for the overall utterance.

Details regarding and scoring were explained in detail in earlier parts of this documentation. Each of the Grammar, Vocabulary, and Coherence feedback metrics has 3 sub-elements:

  1. score: on a scale of 1 to 10

  2. level: an interpretation of the score as low/mid/high

  3. message: a feedback message if the score is low.

In the next few sections, we will review the grammar, vocabulary and coherence scores in detail:
