Extended Data Table 1 Phonetic groupings

From: Single-neuronal elements of speech production in humans

  1. To provide a compositional representation of each word for the main analyses, phonemes were grouped based on their places of articulation for consonants (for example, velar and bilabial) and relative height of the tongue for vowels (for example, high and mid-low). For comparison, phonemes were also grouped based on the manners of articulation (for example, plosive and fricative) as well as the combined position of the tongue and lips for vowels (for example, front-close or back-open). Finally, we used the ten most common syllables in the study’s vocabulary to study the words’ syllabic structures.
