Per metric feedback
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 fluency metrics and sub-scores for the overall utterance and for each segment (sentence) within the utterance. |
word_score_list[] | This node contains pronunciation 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 fluency and pronunciation scoring were explained in detail in earlier parts of this documentation. Each of the Grammar, Vocabulary, and Coherence feedback metrics has 3 sub-elements:
score: on a scale of 1 to 10
level: an interpretation of the score as low/mid/high
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:
