Do phones really exist in conversational speech?
This is an interesting demonstration that allows you to
listen to an utterance transcribed using different linguistic
units. Common recognition units such as
context-dependent phones are included. Can humans really
perceive phones as they are spoken, or does context play
a significant role in our ability to recognize speech?
You make the call! Can you transcribe conversational speech?
This demo contains an archive of many interesting examples
of conversational speech from the
that our expert transcribers found difficult.
Often even a committee of experts found it hard to agree
on the transcription. You can add your comments.
As progress in speech recognition is made each year,
the evaluation tasks become increasingly tougher.
This web page demonstrates how our recognition tasks
have evolved over the past 40 years from simple digit recognition
to complex speech understanding applications.
Conversational speech includes many interesting linguistic phenomena
that result from either cognitive lapses (e.g., restarts, spoonerisms)
or physiological miscues (e.g., vocalized noise).
This web page contains some examples of common problems for
speech recognition systems that appear frequently in
