Check simultaneous pronunciation with CMUdict sound tokens and stress, then practise two original sentences and download a voiceover audition worksheet.

The dictionary sound sequence

CMUdict lists this North American English pronunciation for simultaneous. Read each sequence from left to right. The numbers mark vowel stress: 1 primary, 2 secondary, 0 unstressed.

Check simultaneous in Merriam-Webster and listen to available dictionary audio.

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 simultaneous in context

Simultaneous describes events that happen at the same time. Technical demonstrations, music lessons, and accounts of coordinated actions may depend on that timing. Narration should state which events coincide and avoid suggesting a sequence when the intended meaning is overlap, especially if a listener must reproduce the procedure.

The experiment requires simultaneous measurements at both ends of the tube.
The conductor asked for a simultaneous entrance from the two sections.

Read the sound tokens

Each example word below is a cue for the named sound, rather than a respelling of simultaneous. Unstressed vowels may sound reduced. These cues follow the CMU phoneme-set key (Appendix A).

Ssound in seaconsonant

AYsound in hidevowel

Msound in meconsonant

AHsound in hutvowel

Lsound in leeconsonant

Tsound in teaconsonant

EYsound in atevowel

Nsound in kneeconsonant

ORIGINAL AUDITION SCRIPT
The experiment requires simultaneous measurements at both ends of the tube.
The conductor asked for a simultaneous entrance from the two sections.

REVIEW CHECKLIST
[ ] Read both sentences naturally; keep the source wording.
[ ] Compare the intended pronunciation with the selected dictionary variant.
[ ] Listen for vowel sounds, consonants, and word stress in context.
[ ] Check with a speaker or another dictionary when accent or meaning matters.
[ ] Generate and listen to a short Murmur sample before exporting the full script.

Practice note: Test simultaneous in the complete timing instruction rather than by itself. Listen to the connective words and pauses, checking that the delivery presents the actions as occurring together instead of turning them into separate steps.
