# Handling fluency response
The pronunciation interpretation of the spoken word or sentence remains the same as in the [Score Text/Pronunciation](/api-reference/score-text-pronunciation.md) function. To interpret the fluency quality, refer to the below key elements:
**Overall Fluency Scores**
These scores assist test creators in evaluating the overall fluency of spoken responses, offering insights into the quality of the test-taker's speech. Below is an example of how the fluency score is presented. For detailed interpretation, please refer to the [overall score guide](/guides-on-common-topics/interpreting-overall-scores.md), which includes scales from systems such as IELTS, PTE, and Speechace.
**Fluency Metrics**
The API returns the following feedback metrics under the `fluency` node:
| Field | Description |
| ------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| duration | total length of speech in seconds |
| articulation | total length of articulation (speech minus pauses, hesitations and non-speech events such as laughter). Excludes beginning silence on very first segment and ending silence on very last segment. |
| speech\_rate | speaking rate in syllables per second. |
| syllable\_count | Count of syllables in this segment |
| word\_count | Count of words in this segment |
| correct\_syllable\_count | Count of correctly spoken syllables in this segment |
| correct\_word\_count | Count of correctly spoken words in this segment |
| syllable\_correct\_per\_minute | correct\_syllable\_count / duration in mins |
| word\_correct\_per\_minute | correct\_word\_count / duration in mins |
| all\_pause\_count | count of all pauses (filled and unfilled) which are longer than the minimum pause threshold |
| all\_pause\_duration | total duration of all pauses (filled and unfilled) in seconds |
| all\_pause\_list\[] | a list of all the pauses with the begin/end markers for each in extents of 10 msecs |
| mean\_length\_run | mean length of run in syllables between pauses |
| max\_length\_run | max length of run in syllables between pauses |
| segment\_metrics\_list\[] | A list of segments within the overall text/audio with the fluency metrics for each segment. |
The following are the most commonly used metrics to provide feedback to the user:
1. `word_correct_per_minute`: This measures the count of words per minute. You can color-code the test-taker's rate and compare it to the standard rate of 120 words per minute, which is widely considered the minimum fluent speaking rate.
2. `all_pause_list []`: This is a list of all pauses, with each pause marked by begin and end times, accurate to within 10 milliseconds. Identify and display the locations of medium pause duration (≥500 milliseconds) and long pause duration (>1 second) based on the length and positions of entries in the `all_pause_list[]`.
3. `duration` and `articulation`: Display the duration and articulation length to show how much time the user spent speaking compared to pausing or using fillers.
`a. duration` : The total length of the speech in seconds, including all pauses, fillers, and non-speech events.
`b. articulation`: The total length of actual articulation, calculated as the total speech duration minus pauses, hesitations, non-speech events (such as laughter), and excluding any silence at the very beginning and very end of the speech.
