[Check asthma in Merriam-Webster and listen to available dictionary audio](https://www.merriam-webster.com/dictionary/asthma).

Syllable counts come from vowel tokens; CMUdict does not supply syllable boundaries here. Variant order follows the dictionary and does not rank correctness. This lexicon does not represent every accent or context.

## Use asthma in context

Asthma comes up in health advice, school forms and medical narration. Readers who sound every letter try "ast-ma" or "asth-ma". CMUdict drops the th and voices the s as z.

1. Her asthma gets worse during pollen season.
2. The inhaler helps control asthma attacks.

### A practice cue

Go straight from "az" to "muh" with nothing in between.

## Read the sound tokens

Each example word below is a cue for the named sound, rather than a respelling of asthma. Unstressed vowels may sound reduced. These cues follow the [CMU phoneme-set key (Appendix A)](https://www.cs.cmu.edu/~aria/Papers/MastersThesis.pdf#page=115).

`AE`sound in **at**vowel`Z`sound in **zee**consonant`M`sound in **me**consonant`AH`sound in **hut**vowel
