the phoneme /l/ is one of the phonemes of persian, which has different origins. a few of which is unknown. this article studies the historical change of /l/ phoneme and phonemes and clusters which are the origins of /l/, from proto indo- european to indo- iranian, old iranian and middle and new persian. in adition, the historical change of other phonems such as group of consonants , which are o...

the geometric distribution of states duration is one of the main performance limiting assumptions of hidden markov modeling of speech signals. stochastic segment models, generally, and segmental hmm, specifically, overcome this deficiency partly at the cost of more complexity in both training and recognition phases. in this paper, a new duration modeling approach is presented. the main idea of ...

This paper examines statistical models for phoneme classification. We compare the performance of our phoneme classification system using Gaussian mixture (GMM) phoneme models with systems using hidden Markov phoneme models (HMM). Measurements show that our model’s performance is comparable with HMM models in context independent phoneme classification.

There is a wealth of evidence linking letter knowledge and phoneme awareness, but there is little research examining the nature of this relationship. This article aims to elucidate this relationship by considering the links between letter knowledge and two sub-skills of phoneme awareness: phoneme segmentation and phoneme invariance. Two studies are reported. The first study consisted of an eigh...
