Viking Speech Scale

The Viking Speech Scale was developed to classify children’s speech production using 4 levels. It is developed for use with children aged 4 years and above.

I. Speech is not affected by motor disorder.
II. Speech is imprecise but usually understandable to unfamiliar listeners.
III. Speech is unclear and not usually understandable to unfamiliar listeners out of context.
IV. No understandable speech.

Score children’s usual speech performance i.e. what they usually do, not what they can do.

Score the level to which children are understandable to strangers and unfamiliar conversation partners. People familiar with the children (e.g. parents, teachers) will have "tuned in" to children’s speech, recognise words because of their repeated use in context and may understand the children better than most other listeners.
