  • Hidden Markov model based text to speech systems employing rope-jumping algorithm
    Patent number: 8315871
    Abstract: A rope-jumping algorithm is employed in a Hidden Markov Model based text to speech system to determine start and end models and to modify the start and end models by setting small co-variances. Disordered acoustic parameters due to violation of parameter constraints are avoided through the modification and result in stable line frequency spectrum for the generated speech.
    Type: Grant

  • PRE-SAVED DATA COMPRESSION FOR TTS CONCATENATION COST
    Publication number: 20110246200
    Abstract: Pre-saved concatenation cost data is compressed through speech segment grouping. Speech segments are assigned to a predefined number of groups based on their concatenation cost values with other speech segments. A representative segment is selected for each group. The concatenation cost between two segments in different groups may then be approximated by that between the representative segments of their respective groups, thereby reducing an amount of concatenation cost data to be pre-saved.
