This experimental study investigated aspects of speech rhythm in the Asante-Twi dialect of Akan spoken in Ghana. To uncover prominent elements and their effects on rhythmic coordination, we used the speech cycling methodology, which involved measuring productions of short phrases along with a metronome, thereby creating conditions that allow direct observation of patterns of rhythmic coordination. In eight experiments, several aspects of prosodic structure were investigated under conditions in which speakers attempt to align syllables of phrases in time with an external beat. The units of prominence investigated were H tones (HTs), downsteps, long vowels, CRV structures, word-final and syllabic nasal consonants, and disyllabic words with varying positions of vowels with differing sonority. Prosodic units of interest were manipulated in phrasal position, thus creating different conditions to induce changes in entrainment. In Experiment 1, phrases with all HTs and all LTs were examined, finding no difference in coordination between these tonal patterns. Different patterns emerged in Experiment 2, which manipulated the position of a HT in three different positions within a phrase, and Experiment 3, which manipulated the position of a downstep within a phrase. Experiments 4, 5, and 6 analyzed rhythmic coordination of long vowels, CRV structures, and CVN structures, respectively. Results showed that additional segments contribute to a longer overall duration of a phrase, but also affect coordinative strategies. Experiment 7 explored phrases with six syllables, finding no differences in rhythmic coordination of single HTs. Experiment 8 examined phrases with a change in vowel sonority between two syllables of disyllabic words. The results suggest an influence of vowels differing in sonority on coordination. This study confirms that speakers of Asante-Twi can entrain the syllables of short phrases while speaking along with a metronome. Speakers responded to the two beats of the metronome with a three-beat pattern, thereby creating an overall cross-rhythm, a rhythmic behavior that reflects their cultural experience with Ghanaian music. Furthermore, patterns of stability and consistency emerge when the prosodic units of interest occur in preferred locations within a phrase.
