What is Speech Recognition? Important Answers Revealed

What is speech recognition? Speech recognition is a technology has become extremely popular over the years and currently has a wide range of applications. One common use is its implementation in automated telephone systems, enabling callers to browse through menu options and input choices without pressing any buttons. Speech recognition is also used in homes and businesses where users dictate to their computers and transcribe words into applications such as Microsoft Word or WordPerfect. The technology is being widely used for transcription in legal and medical fields as well.

The Purpose behind Speech Recognition

What is speech recognition's purpose? It's simply the process of converting spoken words into an input that can be interpreted by a machine. The technology also goes by other names, such as voice recognition and automatic speech recognition. Apart from dictation, it serves as a means for giving commands to a computer. With voice instructions, it allows you to command your computer and browse folders, search for specific files or open and close specific programs. It's most common representation is software applications, which enable all of the functions mentioned above.

Speech Recognition Options

What is speech recognition, and what are its options? There are various speech recognition systems available, some of which have a limited vocabulary. Because these systems are specifically designed to recognize the commands of many different people, they are primarily used in telephone answering services. The limitations of such as system may be only giving users the option to answer "yes", "no" or similar commands. Other speech recognition systems have a larger vocabulary, but are user specific, the type of system most often used in the home setting. Although it is able to recognize and follow through on many of the commands it is being dictated, the number of individuals able to use the system effectively is very limited, mainly because such a system requires extensive training.

Improved Dictation

What is speech recognition's progress since its origins? In the beginning, speech recognition was a technology most effective when users spoke clearly with pauses in between each word. This caused a problem for many people, as most of us speak in a continuous manner. Over the years, the technology has improved with software solutions, such as Dragon NaturallySpeaking, which hence the name, allows users to speak in their natural tone and still achieve great accuracy.

Speech Recognition's Technology

What is speech recognition's technology? Speech recognition is a technology that has birthed many new concepts, including speech to text. This process involves a series of steps which begins with an ADC (analog-to-digital) converter that records and converts sound into a digital format compatible with your computer. The system's sampling rate is what determines the quality of a conversion from analog to digital. During the conversion process, any noise the microphone has picked up along with the user's voice is filtered out - sound and volume are adjusted to a consistent level. The speed rate may also be adjusted to compensate the differences in a user's speaking rate and for the computer to compare its RAM files with the digital file. From there, the digital data endures a series of pattern matching with the database in the speech recognition program to accurately transcribe audio into text.

What is speech recognition? It's an old technology that is being continuously developed yet currently offers benefits to various users. Aside from computers and software programs, you can also find speech recognition in mobile phones and even newer model cars. As more businesses and individuals are employing it, one could assume that it will only continue to improve. So what is speech recognition? Something that make your life much easier!
