  • Abstract: The following document tries out different statistical norms to validate the quality of synthesized voices applied to an HTS-based Spanish synthesizer, which uses LSP and Cepstral Coefficients parameterizations. Standard MOS tests were carried out. Nevertheless, other types of quality tests were performed to reinforce the MOS results. Such as: MUSHRA, ABX and CCR. The subjective test PESQ was also applied. To validate intelligibility a SUS test was used.
