    Resumen

    The growing interest in emotional speech synthesis urges effective
    emotion conversion techniques to be explored. This paper
    estimates the relevance of three speech components (spectral
    envelope, residual excitation and prosody) for synthesizing
    identifiable emotional speech, in order to be able to customize
    the voice conversion techniques to the specific characteristics
    of each emotion. The analysis has been based on listening a set
    of synthetic mixed-emotional utterances that draw their speech
    components from emotional and neutral recordings. Results
    prove the importance of transforming residual excitation for the
    identification of emotions that are not fully conveyed through
    prosodic means (such as cold anger or sadness in our Spanish
    corpus).
