Classification performance for emotional user states found in the few realistic, spontaneous databases available is as yet not very high. We present a database with emotional children’s speech in a human-robot scenario. Baseline classification performance for seven classes is 44.5%, for four classes 59.2%. We discuss possible strategies for tuning, e.g., using only prototypes (based on annotati...

In this study, the robustness of approaches to the automatic classification of emotions in speech is addressed. Among the many types of emotions that exist, two groups of emotions are considered, adult-to-adult acted vocal expressions of common types of emotions like happiness, sadness, and anger and adult-to-infant vocal expressions of affective intents also known as ‘‘motherese’’. Specificall...

The Utsunomiya University (UU) Spoken Dialogue Database for Paralinguistic Information Studies is introduced. The UU Database is especially intended for use in understanding the usage, structure and effect of paralinguistic information in expressive Japanese conversational speech. Paralinguistic information refers to meaningful information, such as emotion or attitude, delivered along with ling...

In this paper, we present a novel texture image feature for Emotion Sensing in Speech (ESS). This idea is based on the fact that the texture images carry emotion-related information. The feature extraction is derived from time-frequency representation of spectrogram images. First, we transform the spectrogram as a recognizable image. Next, we use a cubic curve to enhance the image contrast. The...

The human speech contains and reflects information about the emotional state of the speaker. The importance of research of emotions is increasing in telematics, information technologies and even in health services. The research of the mean acoustical parameters of the emotions is a very complicated task. The emotions are mainly characterized by suprasegmental parameters, but other segmental fac...

Fast and holistic access to the patients’ clinical record is a major requirement of modern medical decision support systems (DSS). While electronic health records (EHRs) have replaced the traditional paper-based records in most healthcare organization, the data entry into these systems remains largely manual. Speech recognition technology promises substitution of the more convenient speech-base...

Cochlear implant (CI) speech performance is typically evaluated using well-enunciated speech produced at a normal rate by a single talker. CI users often have greater difficulty with variations in speech production encountered in everyday listening. Within a single talker, speaking rate, amplitude, duration, and voice pitch information may be quite variable, depending on the production context....

This paper describes an emotional speech database recorded for standard Basque. This database was recorded in the framework of a project in which the goal was to develop an avatar. therefore, the image corresponding to the expression of the different emotions was also needed. This is why an audiovisual database was developed. The designed database contains six basic emotions as well as the neut...

Two well-known variants of the self-organizing map (SOM) that are based on order statistics are the marginal median SOM and the vector median SOM. In the past, their efficiency was demonstrated for color image quantization. In this paper, we employ the well-known IRIS data set and we assess their performance with respect to the accuracy, the average over all neurons mean squared error between t...
