Recording Lifecycle
This is an umbrella term for all audio recordings in the audio sample library, including raw recordings, validated recordings, modified recordings, and test clips.
What is an audio sample?
This is a person who has consented to being recorded.
What is a volunteer?
“Punctuated” and “continuous” are two kinds of this.
What is background noise?
This is the length of an IP CTS test cycle.
What is 6 months?
These are the two thigs that will be measured for captions using the v1 metric.
What are accuracy and delay?
This is a complete, unmodified, unvalidated audio recording of a conversation. Test clips are derived from it after they are validated and modified.
What is a raw recording?
This is the human or artificial entity that converses with a volunteer in a recorded conversation.
What is a confederate??
“Um” and “uh” are two examples of these.
What are disfluencies?
This is the percentage of test calls per cycle that are high complexity.
What is 50%?
This is the “ground truth” against which captions are compared.
What is a reference transcript?
This is a raw recording that has been reviewed and is approved for modification prior to becoming a test clip.
What is a validated recording?
This is the purpose for which a conversation took place or the type of interaction that occurred (e.g., filling a prescription, placing a customer service call)
What is a scenario?
This is defined as the tempo of speech excluding pauses and hesitations, measured in words per minute.
What is articulation rate?
This is the minimum number of test clips used per test cycle.
What is 60?
This occurs when a person changes the volume or pitch of their voice to compensate for background noise.
What is the Lombard Effect?
This is a validated recording that has undergone modification (such as the addition of background noise) but has not yet been trimmed to form a test clip.
What is a modified recording?
This is the overall subject matter of a conversation.
What is domain?
This is a commonly used measure of vocabulary complexity.
What is Flesch-Kincaid?
This is initiated when a provider disagrees with how a test call has been scored.
What is the challenge process?
These three things are tallied when calculating Word Error Rate.
What are substitutions, deletions, and insertions?
This is a validated recording that is derived from a raw recording, has undergone modification, and is ready to be used in an IP CTS test call
What is a test clip?
This is calculated by multiplying a recording’s Speech and Channel Complexity Score (SCCS) by its intelligibility multiplier.
What is a complexity score?
This is the percentage of the recording that is speech, calculated by dividing the total duration of speech (excluding silences) by the total duration of the recording.
What is speaking ratio?
This is the number of days within which a results package must be posted after the end of a test cycle.
What is 120?
This is the time increment in which caption delay is measured.
What is 0.1 seconds?
