GOORE 2 Ecole Supérieure Africaine des Technologies d’Information et de Communication (ESATIC), Abidjan, Côte d’Ivoire In this article, we are presenting the work we did in the context of the recognition of "Baoule" Language spoken phrases. Since we consider a particular case of the problem, we therefore will only take into account the vowel-consonant transition, while stopping on the Phoneme recognition. We are proposing a Phoneme separation algorithm, based on the consonants and vowels energy levels difference. We are also proposing a recognition algorithm by analysing the formants. http://pubs.sciepub.com/ajmo/4/2/1/ajmo-4-2-1.pdf FFT(Fast Fourier Transform) spectograms formants phomemes vocal trapeze convolution Harmin Window
