2. 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)
3. 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
6. 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
7. 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
