the speech signal is obtained after the process of

developed speech-based HRI systems based on robot-directed speech to study the conceptualizations of robots [38,39]. There are a number of factors to consider when delivering your speech that can help or hinder your efforts to an effective overall presentation. Large-vocabulary, audiovisual ASR results using the IBM (left) and NWU (right) systems. The key then, to understanding your context is to develop a habit of situational awareness. The encoded signal is made suitable for transmission by modulation onto a carrier wave and may be made part of a larger signal in a process known as multiplexing. In RoboCup 2008, Doostdar et al. The third effect on the signal caused by increasing the distance between speaker and microphone is the topic of this chapter: In an enclosure, the source signal will travel via multiple paths to the sensor. The representative technologies for both GMMs and DNNs are described. A basic speech communication model includes a sender (that is, a speaker), a message, a receiver (that is, an audience), and a channel. The filter design is an FIR lowpass filter with order equal to 20 and a cutoff frequency of 150 Hz. However, it not an easy job and in fact, the trickiest. When considering both gender and cultural contexts, we often encounter bias, both intentional and unintentional, and implicit or explicit. Hands-free automatic speech recognition in a reverberant enclosure: the source signal travels via a direct path and via single or multiple reflections to the microphone. The filter design is an FIR lowpass filter with order equal to 20 and a cutoff frequency of 150 Hz. When it comes to public speaking, noise and interference can be a major issue for both you as message sending and for your audience as your message receivers. Claude Shannon, who developed one of the earlier communication models, defined the channel as the medium used to transmit the signal from the transmitter to the receiver. The channel might also be asynchronous, when audiences listen to the speech at some time after the speech was delivered, perhaps via a website like youtube.com or vimeo.com. Noise and interference block the sending or receiving of a message. Consider, for example, an interactive TV scenario with one person controlling the TV by voice and others in the room engaged in a conversation, or children playing in the background. It thus requires dedicated approaches which are quite different from what is done to combat additive noise or channel distortions that extend over just a single time frame. For some applications, we just need to undo the boosting at the end. Reverberation refers to this process of multipath propagation. The channel is the method (auditory and visual) that is used to transmit the message to the receiver. The sender is the initiator of communication. The best results are obtained by a hybrid fusion approach that uses the two-stream HMM (AV-MS) framework to combine audio features with fused audiovisual discriminant features (AV-Discr. Within each of these broad areas are several types of tasks. Environmental and Situational Context: The environmental and situational context in which you give a speech is important. Segmentation covers the distinction of different types of sound such as speech, music, silence, and environmental sounds. Indeed, freeing the user from holding or wearing a microphone will not only increase usability. Kriz et al. You might need to physically project your voice a little more to be heard over a low din. Below is the before and after signal on how the high-frequency signal is boosted. Communication Theory/Nonverbal Communication. Language processing—processing the meaning of verbal input.
