Definition

1. Noun:
   • A reduced vowel sound: A "murmur vowel" is a very short, weak, and unstressed vowel sound, specifically a schwa, that occurs as a byproduct of articulating a consonant, rather than being a full, intentional vowel in a word's syllable structure.

Usage

• The term "murmur vowel" is a technical term used in phonetics and linguistics to describe a specific phonetic phenomenon. It is not used in everyday conversation.
• It is used to analyze and describe the subtle, often imperceptible, vowel-like sounds that can be heard during the transition between certain consonants.

Examples

• Noun:
  • The linguist noted the presence of a murmur vowel between the two plosive consonants.
  • In rapid speech, a murmur vowel may be inserted, making "film" sound like "filum".

Advanced Usage

• Phonetic Context: In detailed phonetic transcription, a murmur vowel might be represented to account for the audible transition in consonant clusters, especially where the vocal cords continue to vibrate briefly.
  • The analysis showed that the syllable-final /l/ was followed by a murmur vowel before the next word began.

Variants and Related Words

• Schwa (n): The mid-central vowel sound /ə/, which is the most common reduced vowel in English and often what a "murmur vowel" manifests as.
  • The schwa is the sound of the 'a' in 'about'.
• Epenthetic Vowel (n): A vowel inserted into a word to break up a consonant cluster, which can sometimes be a murmur vowel.
  • The epenthetic vowel in "athlete" pronounced as "ath-uh-lete" is a type of murmur vowel.

Synonyms

• Transitional Vowel: A vowel sound occurring as a transition between consonants.
• Excrescent Schwa: An extra, inserted schwa sound.

Related Terms (Phonetics)

• Voice Onset Time (VOT): The timing of vocal cord vibration relative to a consonant release; murmur vowels can occur during the voiced portion of certain consonants.
• Sonorant: A class of sounds (like nasals, liquids, glides) during which a murmur vowel is more likely to occur due to continuous voicing.

Noun

1. a schwa that is incidental to the pronunciation of a consonant
