Speech recognition

Speech recognition
Speech recognition is usually processed in middleware, the results are transmitted to the user applications. In Computer Science and Electrical Engineering speech recognition (SR) is the translation of spoken words into text. It is also known as "automatic speech recognition" (ASR), "computer speech recognition", or just "speech to text" (STT). Some SR systems use "speaker independent speech recognition"[1] while others use "training" where an individual speaker reads sections of text into the SR system. These systems analyze the person's specific voice and use it to fine tune the recognition of that person's speech, resulting in more accurate transcription. Systems that do not use training are called "speaker independent" systems. Speech recognition applications include voice user interfaces such as voice dialling (e.g. The term voice recognition[2][3][4] or speaker identification[5][6] refers to finding the identity of "who" is speaking, rather than what they are saying.

Sprach-Interaktion Allgemeines[Bearbeiten] Sprach-Interaktion ist ein immer beliebter werdendes Thema, was auch Blinden oder Körperlichbehinderten zu gute kommt. Es ermöglicht das Vorlesen und Diktieren von Texten, sowie das Steuern ganzer Systeme. Definitionen[Bearbeiten] Spracherkennung wird im Allgemeinen mit SR (Speech Recognition) abgekürzt. Sprachsynthese wird im Allgemeinen mit TTS (Text to Speech) abgekürzt.

But, for some people, the small size of a phone's keyboard or touch screen can be limiting and difficult to use. If you have trouble seeing the small type, have a lack of finger dexterity or just think better out loud, you might benefit from a tool that allows you to convert spoken words to written words. 1. Once the app has transcribed your speech, you can send it out via email or copy and paste to another application. 2. Unlike Dragon Dictation, Evernote saves both the audio and the text file together so you can use the app's search ability to find a recorded note. The app is free, but because Evernote uses Google Android's text transcription service, you do need to be online to use it. 3. Use the auto copy feature to send your transcriptions to other apps such as Google Search, YouTube, Evernoteor Pages. The app costs 99 cents and is available for the iPhone and iPad.

Hidden Markov model In simpler Markov models (like a Markov chain), the state is directly visible to the observer, and therefore the state transition probabilities are the only parameters. In a hidden Markov model, the state is not directly visible, but output, dependent on the state, is visible. Each state has a probability distribution over the possible output tokens. Therefore the sequence of tokens generated by an HMM gives some information about the sequence of states. Note that the adjective 'hidden' refers to the state sequence through which the model passes, not to the parameters of the model; the model is still referred to as a 'hidden' Markov model even if these parameters are known exactly. Hidden Markov models are especially known for their application in temporal pattern recognition such as speech, handwriting, gesture recognition,[7] part-of-speech tagging, musical score following,[8] partial discharges[9] and bioinformatics.

Voice command device Newer VCDs are speaker-independent, so they can respond to multiple voices, regardless of accent or dialectal influences. They are also capable of responding to several commands at once, separating vocal messages, and providing appropriate feedback, accurately imitating a natural conversation.[1] They can understand around 50 different commands and retain up to 2 minutes of vocal messages.[1] VCDs can be found in computer operating systems, commercial software for computers, mobile phones, cars, call centers, and internet search engines such as Google. In 2007, a CNN business article reported that voice command was over a billion dollar industry and that companies like Google and Apple were trying to create voice recognition features.[2] It has been years since the article was published, and since then the world has witnessed a variety of voice command devices.

Originally, relay services were designed to be connected through a TDD (TTY) or other assistive telephone device. Services have gradually expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first relay service was established by Converse Communications of Connecticut in 1974. Types of service available[edit] Depending on the technical and physical abilities, as well as physical environments, of users, different call types are possible via relay services. TTY to Voice/Voice to TTY[edit] Voice Carry Over[edit] A common kind of call is Voice Carry Over (VCO). VCO with privacy[edit] 2-Line VCO[edit]

Sprachsteuerung Als Sprachsteuerung bezeichnet man die Übermittlung von Befehlen an technische Geräte, die per Stimme erfolgt. Grundsätzlich kann das Prinzip der Sprachsteuerung bei einer sehr großen Zahl von Gerätetypen zum Einsatz kommen. Voraussetzung ist, dass es ein Modul für Spracherkennung gibt, das sprachliche Äußerungen aufnehmen und interpretieren kann. Bisherige Einsatzbereiche[Bearbeiten] Sprachsteuerung wird außerdem auch bei Navigationssystemen in Pkws eingesetzt. Softwareauswahl[Bearbeiten] Siehe auch[Bearbeiten]
