Handling phoneme and syllable scores

Last updated 7 months ago

Just as we have word-level pronunciation quality scores, we also assess pronunciation at the phoneme and syllable levels:

Additionally, the lexical stress level measures how accurately the stressed syllables or phonemes in a word are pronounced compared to the expected stress pattern. In this context, stress_level represents the expected stress level, while predicted_stress_level indicates the actual stress level determined by the pronunciation evaluation. Possible values are:

  1. 0: unstressed

  2. 1: primary stress

  3. 2: secondary stress

Note that lexical stress score evaluates the quality of stress applied to syllables or phonemes, ranging from 0 to 100. A higher score indicates better accuracy in stress placement according to the expected pattern.

Lastly note the Sound most like values, which indicate how the pronounced phoneme sounded compared to the expected phoneme.
