# Handling phoneme and syllable scores
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.
