Voice Search
Voice search, also called voice-enabled search, allows the user to use a voice command to search the Internet, a website, or an app. In a broader definition, voice search includes open-domain keyword query on any information on the Internet, for example in Google Voice Search, Cortana, Siri and Amazon Echo. Voice search is often interactive, involving several rounds of interaction that allows a system to ask for clarification. Voice search is a type of dialog system. Voice search is not a replacement for typed search. Rather the search terms, experience and use cases can differ heavily depending on the input type. Supported language Language is the most essential factor for a system to understand, and provide the most accurate results of what the user searches. This covers across languages, dialects, and accents, as users want a voice assistant that both understands them and speaks to them understandably. While spoken and written languages differ, voice search should support ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Voice Command
Speech recognition is an interdisciplinary subfield of computer science and computational linguistics that develops methodologies and technologies that enable the recognition and translation of spoken language into text by computers. It is also known as automatic speech recognition (ASR), computer speech recognition or speech-to-text (STT). It incorporates knowledge and research in the computer science, linguistics and computer engineering fields. The reverse process is speech synthesis. Some speech recognition systems require "training" (also called "enrollment") where an individual speaker reads text or isolated vocabulary into the system. The system analyzes the person's specific voice and uses it to fine-tune the recognition of that person's speech, resulting in increased accuracy. Systems that do not use training are called "speaker-independent" systems. Systems that use training are called "speaker dependent". Speech recognition applications include voice user interfaces s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Google Voice Search
Google Voice Search or Search by Voice is a Google product that allows users to use Google Search by speaking on a mobile phone or computer, i.e. have the device search for data upon entering information on what to search into the device by speaking. Initially named as Voice Action which allowed one to give speech commands to an Android phone. Once only available for the U.S. English locale – commands were later recognizable and replied to in American, British, and Indian English; Filipino, French, Italian, German, and Spanish. In Android 4.1+ (Jelly Bean), it was merged with Google Now. In August 2014, a new feature was added to Google Voice Search, allowing users to choose up to five languages and the app will automatically understand the spoken language.

Amazon Echo
Amazon Echo, often shortened to Echo, is a brand of smart speakers developed by Amazon (company), Amazon. Echo devices connect to the voice-controlled Virtual assistant, intelligent personal assistant service. ''Amazon Alexa, Alexa'', which responds to a wake term (''Alexa'', and others) when spoken by its user. The features of the device include voice interaction, audio program playback, such as music, streaming podcasts, and audiobooks, maintaining to-do lists, Alarm device, alarms, and scheduling reminders. in addition to providing weather, traffic and other real-time information. It can also control several smart devices, acting as a home automation hub. Amazon started developing Echo devices inside its Amazon Lab126, Lab126 offices in Silicon Valley and in Cambridge, Massachusetts as early as 2010. The device represented one of its first attempts to expand its device portfolio beyond the Amazon Kindle, Kindle e-reader. Amazon initially limited the first-generation Echo to A ...

Dialog Systems
A dialogue system, or conversational agent (CA), is a computer system intended to converse with a human. Dialogue systems employed one or more of text, speech, graphics, haptics, gestures, and other modes for communication on both the input and output channel. The elements of a dialogue system are not defined because this idea is under research, however, they are different from chatbot. The typical GUI wizard engages in a sort of dialogue, but it includes very few of the common dialogue system components, and the dialogue state is trivial. Background After dialogue systems based only on written text processing starting from the early Sixties, the first ''speaking'' dialogue system was issued by the DARPA Project in the US in 1977. After the end of this 5-year project, some European projects issued the first dialogue system able to speak many languages (also French, German and Italian).Alberto Ciaramella, ''A prototype performance evaluation report'', Sundial work package 8000 ...

Natural-language Understanding
Natural language understanding (NLU) or natural language interpretation (NLI) is a subset of natural language processing in artificial intelligence that deals with machine reading comprehension. NLU has been considered an AI-hard problem. There is considerable commercial interest in the field because of its application to automated reasoning, machine translation, question answering, news-gathering, text categorization, voice-activation, archiving, and large-scale content analysis. History The program STUDENT, written in 1964 by Daniel Bobrow for his PhD dissertation at MIT, is one of the earliest known attempts at NLU by a computer. Eight years after John McCarthy coined the term artificial intelligence, Bobrow's dissertation (titled ''Natural Language Input for a Computer Problem Solving System'') showed how a computer could understand simple natural language input to solve algebra word problems. A year later, in 1965, Joseph Weizenbaum at MIT wrote ELIZA, an interact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text To Speech
Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech. The reverse process is speech recognition. Synthesized speech can be created by concatenating pieces of recorded speech that are stored in a database. Systems differ in the size of the stored speech units; a system that stores phones or diphones provides the largest output range, but may lack clarity. For specific usage domains, the storage of entire words or sentences allows for high-quality output. Alternatively, a synthesizer can incorporate a model of the vocal tract and other human voice characteristics to create a completely "synthetic" voice output. The quality of a speech synthesizer is judged by its similari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multimodal Interaction
Multimodal interaction provides the user with multiple modes of interacting with a system. A multimodal interface provides several distinct tools for input and output of data. Multimodal human-computer interaction involves natural communication with virtual and physical environments. It facilitates free and natural communication between users and automated systems, allowing flexible input (speech, handwriting, gestures) and output (speech synthesis, graphics). Multimodal fusion combines inputs from different modalities, addressing ambiguities. Two major groups of multimodal interfaces focus on alternate input methods and combined input/output. Multiple input modalities enhance usability, benefiting users with impairments. Mobile devices often employ XHTML+Voice for input. Multimodal biometric systems use multiple biometrics to overcome limitations. Multimodal sentiment analysis involves analyzing text, audio, and visual data for sentiment classification.

SpeechWeb
A SpeechWeb is a collection of hyperlinked speech applications, accessed remotely by speech browsers running on end-user devices. Links are activated through spoken commands. History The idea of surfing the World Wide Web, web by voice dates back to at least the work of Hemphill and Thrift in 1995 Hemphill, C.T. and Thrift, P. R.Surfing the Web by Voice" ''Proceedings of the third ACM International Multimedia Conference (San Francisco 1995)'', Year: 1995, Pages: 215 – 222. who developed a system in which, HTML pages were downloaded and processed on client-side computers enabling voice access to web page content, and activation of hyperlinks through spoken commands. Also in the mid 1990s, researchers at AT&T were discussing the development of a new markup language that would enable the web to be accessed through regular phones. From 1995 to 1999, AT&T, Lucent, Motorola, and IBM all developed their own versions of phone and speech markup languages. These companies created thVoiceX ...

Query By Humming
Query by humming (QbH) is a music retrieval system that branches off the original classification systems of title, artist, composer, and genre. It normally applies to songs or other music with a distinct single theme or melody. The system involves taking a user-hummed or whistled melody (input query) and comparing it to an existing database. The system then returns a ranked list of music closest to the input query. One example of this would be a system involving a portable media player with a built-in microphone that allows for faster searching through media files. The MPEG-7 standard includes provisions for QbH music searches. Examples of QbH systems include ACRCloud, SoundHound, Musipedia, Tunebot and Google Search.
