Basic standards

Key standards

Visual physical commonsense (V-PC)

• The person says the target word 'apple' three distinct times with visible mouth articulation, with vocal effort visibly escalating from a whisper-like mouth shape through normal speech to a shout.

Audio physical commonsense (A-PC)

• The loudness of the spoken word increases monotonically across the three utterances, from a barely-audible whisper through normal conversational volume to a loud strained shout.

Cross-modal physical commonsense (AV-PC)

• Each spoken 'apple' onset aligns in time with a visible mouth articulation.
• The loudest utterance corresponds to the strongest visible vocal effort.
• The softest utterance corresponds to the gentlest visible vocal effort.
