| Overview | |
| This CSTR VCTK Corpus includes speech data uttered by 109 English | |
| speakers with various accents. Each speaker reads out about 400 | |
| sentences, which were selected from a newspaper, the rainbow passage | |
| and an elicitation paragraph used for the speech accent archive. | |
| The newspaper texts were taken from Herald Glasgow, with permission | |
| from Herald & Times Group. Each speaker has a different set of the | |
| newspaper texts selected based a greedy algorithm that increases the | |
| contextual and phonetic coverage. | |
| The rainbow passage and elicitation paragraph are the same for all | |
| speakers. The rainbow passage can be found at International Dialects | |
| of English Archive: | |
| (http://web.ku.edu/~idea/readings/rainbow.htm). The elicitation | |
| paragraph is identical to the one used for the speech accent archive | |
| (http://accent.gmu.edu). The details of the the speech accent archive | |
| can be found at | |
| http://www.ualberta.ca/~aacl2009/PDFs/WeinbergerKunath2009AACL.pdf | |
| All speech data was recorded using an identical recording setup: an | |
| omni-directional microphone (DPA 4035), 96kHz sampling frequency at 24 | |
| bits and in a hemi-anechoic chamber of the University of | |
| Edinburgh. All recordings were converted into 16 bits, were downsampled | |
| to 48 kHz based on STPK, and were manually end-pointed. | |
| This corpus is aimed for HMM-based text-to-speech synthesis systems, | |
| especially for speaker-adaptive HMM-based speech synthesis that uses | |
| average voice models trained on multiple speakers and speaker | |
| adaptation technologies. | |
