Product Description
These printable picture/word cards utilize minimal opposition to facilitate the correct production of /s/-stop blends. They are more phonetically consistent than the great bulk of therapy materials designed for this purpose. The rationale behind this claim is explained briefly below and in more depth in the preview file.

Background information:

The primary difference between a voiced and voiceless stop in initial position is voice onset time (VOT) or the amount of time between the release of the stop and the beginning of vocal fold vibration.

If VOT is long, you hear a voiceless stop.

If VOT is short, you hear a voiced stop.

Adding an /s/ to the stops in “spot, skate, & stop” shortens VOT significantly, making the /p, k, t/ sound more like /b, g, d/.

If the spelling matched the actual sounds produced, the above blends would be spelled “sbot, sgate, & sdop.”

Spelling and IPA transcription conventions bias how readers hear these sounds, often blinding them to more phonetically consistent relationships.


True minimal pairs result from contrasting /s/-stop blends with voiced, stop singletons, i.e., skate-gate.

Pairing /s/-stop blends with voiceless stops (skate-Kate) requires clients to both deaspirate the plosive and shorten VOT.

Both SLP and client may be blind to these processes.

Pairing /s/-stop blends with voiced stop singletons removes an unnecessarily complex transformation and better focuses treatment on the target skill.

Clients who respond to Kate-skate pairings may produce a distorted /s/-blend before producing the adult-like form. Gate/skate pairings, as discussed here, may skip this intermediate step and result in easier elicitation and faster scaffolding.
