Read each sequence from left to right. The numbers mark vowel stress: **1** primary, **2** secondary, **0** unstressed. Dictionary variant 1 `M AH0 L IH1 B D IH0 N AH0 M` **Syllable estimate** 4 vowel nuclei **Primary stress** 2nd vowel position [Check molybdenum in Merriam-Webster and listen to available dictionary audio](https://www.merriam-webster.com/dictionary/molybdenum). 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 molybdenum in context Molybdenum is a metal named in chemistry classes, steel specs and soil reports. Its cluster of consonants leads readers to drop a syllable or stress the first one. All four syllables are sounded, with the weight on the second. 1. Molybdenum is added to steel to make it stronger at high heat. 2. The soil test showed low levels of molybdenum. ### A practice cue Go slowly at first: muh-LIB, then dih-num, with the b and d as two separate taps. Speed up only once all four beats are steady. Most slips happen when the b gets swallowed. ## Read the sound tokens Each example word below is a cue for the named sound, rather than a respelling of molybdenum. 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). `M`sound in **me**consonant`AH`sound in **hut**vowel`L`sound in **lee**consonant`IH`sound in **it**vowel`B`sound in **be**consonant`D`sound in **dee**consonant`N`sound in **knee**consonant Take it to your next recording ## Make an audition worksheet Select a dictionary variant for your checklist.
