In this paper, a structural maximum a posteriori (SMAP) speaker adaptation approach to adjusting the speaking rate (SR)-dependent hierarchical prosodic model (SR-HPM) of an existing SR-controlled Mandarin text-to-speech system to a new speaker's data for producing a new voice is discussed. Two main issues are addressed. One is the small SR coverage of the adaptation data and is solved by using the...
High quality linguistic features extraction is the key component to the success of speech synthesis. However, traditional linguistic feature extraction methods are all based on natural language processing (NLP) frontends that relies heavily on feature engineering and ignores backend synthesis errors in feedback. In order to approach the goal of establishing an end-to-end speech synthesis system, in...
In this paper, the prosody of a parallel multispeaking rate Mandarin read speech corpus is investigated. The corpus contains four parallel speech datasets uttered by a female professional announcer with various speech rates (SRs) of 4.40 (fast), 3.82 (normal), 2.97 (median) and 2.45 (slow) syllables/second. By using the unsupervised joint prosody labeling and modeling (PLM) method proposed previously,...
In this paper, the high-level prosodic patterns of prosodic word (PW), prosodic phrase (PPh) and breath group/prosodic phrase group (BQ/PQ) for syllable pitch-level and duration are explored using an automatic joint prosody labeling and modeling method. Experimental results on a treebank speech corpus showed that the explored high-level prosodic patterns not only matched well with our a priori knowledge...
