Voice conversion between UK and US accented English

چکیده
This paper presents an HMM-based method and experimental results for voice conversion between UK and US accented English. Phonetic-tree based tiedstate triphone HMMs are used to map equivalent states of the source and target spectra. Then a linear transformation method is incorporated to estimate the most likely target spectra for a given input. The mapping is between two different sets of phoneme i.e. the 44-phoneme UK English BEEP phone set and 39phoneme US CMU phone set. Finally, a prosody adaptation is applied to tune the prosodic parameters. The experiments are based on voice conversion between speakers speaking different unrestricted texts. Acoustic-phonetic mapping between two different accents database enables us to attempt to deconstruct accents to investigate how they are distributed among different parameters such as spectra, energy contour, pitch, and duration.

Towards a flexible platform for voice accent and expression selection on a Healthcare Robot
In the application of robots in healthcare, where there is a requirement to communicate vocally with non-expert users, a capacity to generate intelligible and expressive speech is needed. The Festival Speech Synthesis System is used as a framework for speech generation on our healthcare robot. Expression is added to speech by modifying mean pitch and pitch range parameters of a statistical mode...
متن کاملPROCESSING TIME EFFECTS OF SHORT-TERM EXPOSURE TO FOREIGN-ACCENTED ENGLISH by Constance
Non-native speech can cause perceptual difficulty for the native listener, but experience can moderate this difficulty. This study explored the perceptual benefits of brief exposure to non-native speech. A cross-modal word matching paradigm was used to investigate perception of foreign-accented speech by native English listeners during the first moments of exposure. In 5 experiments, processing...
متن کاملSocial Evaluation of Asian Accented English
This paper examines evaluations of Asian accented English by American listeners. Despite widely circulating stereotypes about Asian accents, and the substantial body of work on attitudes toward different language varieties, relatively few studies have looked at American attitudes toward Asian accented English, and those that exist have produced rather ambiguous results. In an online survey, res...
متن کاملVoice morphing and the manipulation of intra-speaker and cross-speaker phonetic variation to create foreign accent continua: a perceptual study
The STRAIGHT system of voice morphing was used to create voice continua of (Korean) accented Australian English, intended to simulate phonetic variation ranging from ‘heavily accented’ to ‘unaccented’ (native-like) Australian English, employing dimensions of intra-speaker and cross-speaker variation to yield a range of synthetic voices. These synthetic voices were evaluated against actual sampl...

The Blizzard Challenge 2008 was the fourth annual Blizzard Challenge. This year, participants were asked to build two voices from a UK English corpus and one voice from a Mandarin Chinese corpus. This is the first time that a language other than English has been included and also the first time that a large UK English corpus has been available. In addition, the English corpus contained somewhat...
