An analysis-by-synthesis method for finding formant bandwidths from vowel spectra has been implemented on a solar-powered computer used in fieldwork, thus enabling linguists to test hypotheses about differences between sets of vowels while working with speakers of the language. The procedure has been tested on the two sets of vowels that occur in Degema, a language spoken in Nigeria.
