It has been shown that techniques known as grapheme-and-phoneme-to-phoneme (GP2P) conversion can be used to derive pronunciations in a poorly-resourced accent, such as South African English, using available pronunciations in better-resourced accents of the same language, such as British and American English. However if the pronunciation is not available in either accent, it must be obtained usi...

We present results from a series of 151 speech recognition experiments based on the N4 corpus of accented English speech, using a small vocabulary recognition system. These experiments looked at the impact of foreign accent on speech recognition, both within non-native accented English and across different accents, with particular interest in using context free grammar technology to improve cal...

The differences between formants of British, Australian and American English accents are analysed and ranked. An improved formant model based on linear prediction (LP) feature analysis and a two-dimensional(2D) hidden Markov model (HMM) of formants is employed for estimation of the formant frequencies and bandwidths of vowels and diphthongs. Comparative analysis of the formant trajectories, the...

Intonation languages signal pragmatic functions (e.g. information structure) by means of different pitch accent types. Acoustically, pitch accent types differ in the alignment of pitch peaks (and valleys) in regard to stressed syllables, which makes the position of pitch peaks an unreliable cue to lexical stress (even though pitch peaks and lexical stress often coincide in intonation languages)...

It is very common for a language to have different dialects or accents. The different pronunciations of the same words is one of the reasons for the different accents, in the same language. Swiss French accents have similar pronunciation to standard French, but noticeable differences in prosody. In this paper we investigate the use of standard French synthetic acoustic parameters combined with ...

Accent is the basic pattern of acoustic feature and pronunciation. It can identify the person’s social and linguistic background. It is an important source of inter as well as intra speaker variability. The accent dependent dictionary or model can be used to improve accuracy of speech recognition system. In this study we present an experimental approach of acoustic speech feature for Marathi & ...

In many embedded systems commands and other words in the user’s main language must be recognized with maximum accuracy, but it should be possible to use foreign names as they frequently occur in music titles or city names. Example systems with constrained resources are navigation systems, mobile phones and MP3 players. Speech recognizers on embedded systems are typically semi-continuous speech ...

Some big languages like English are spoken by a lot of people whose mother tongues are different from. Their second languages often have not only distinct accent but also different lexical and syntactic characteristics. Speech recognition performance is severely affected when the lexical, syntactic, or semantic characteristics in the training and recognition tasks differ. Language model of a sp...
