Abstract

This paper describes the use of statistical techniques and hidden Markov models (HMM) in the recognition of emotions. The method aims to classify 6 basic emotions (anger, dislike, fear, happiness, sadness and surprise) from both facial expressions (video) and emotional speech (audio). The emotions of 2 human subjects were recorded and analyzed. The findings show that the audio and video information can be combined using a rule-based system to improve the recognition rate.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Relatively few efforts have focused on emotion recognition using both facial expressions and acoustic information.

    “Although several automatic emotion recognition systems have explored the use of either facial expressions [1],[11],[16],[21],[22] or speech [9],[18],[14] to detect human affective states, relatively few efforts have focused on emotion recognition using both modalities [4],[8].”
  • None of the previous papers attempted to compare which fusion approach is more suitable for emotion recognition.

    “However, none of these papers attempted to compare which fusion approach is more suitable for emotion recognition.”
  • The performance of emotion recognition systems can be improved by the use of multimodal information.

    “All these studies have shown that the performance of emotion recognition systems can be improved by the use of multimodal information.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
