Speech recognitionBy: Rachel Fernandes and Kaitlyn Bryson

What is speech recognition?

Speech Recognition (SR) is the ability to translate a dictation or spoken word to text.

Also known as “automatic speech recognition” (ASR), “computer speech recognition”, or “speech to text” (STT)

How it works...

Spoken communication is delivered via a microphone

Sound waves are converted into digital format

Software analyzes input and breaks down message

Software gives an output based on what it perceives and it will be displayed on a computer screen or phone screen

Process

Here’s another look at how SRS works...

The many uses of SRS

Pros of speech recognition

Faster than “hand-writing”

Allows for better spelling, whether it be in text or documents

Helpful for people with a mental or physical disability

Hands-free capability

Cons of speech recognition

No program is 100% perfect

Factors that affect the accuracy of speech recognition are: slang, homonyms, signal-to-noise ratio, and overlapping speech

Can be expensive depending on the program

For example, MacSpeech Dictate had the lack of a transcription feature for recorded voice dictation
