Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomised to receive either one of two levels of supplemental language exposure in the form of recorded maternal voice, delivered by microspeaker. The intervention will take place in the single-room designed Neonatal Intensive Care Unit and Special Care Nursery of the Gold Coast University Hospital. The intervention group will receive a treatment level of exposure of 6000 words/hour and the control group will receive a low-dose of 600 words/hour within a developmental appropriate decibel range. Each group will receive the exposure over one hour, three times daily. The mother of each enrolled participant will be asked to read a short story selected by the research team, for ten minutes. This recording will be processed using a software program to convert the 10 minute reading into an mp3 recording which will automatically play the desired 'dose' throughout the day at three 1-hour intervals. A team of research nurses enrolled in the study will be responsible for pressing play on the recording in the morning.

Comparator / control treatment
The control group will receive a placebo level of language exposure of 600 words/hour within a developmental appropriate decibel range. The control group will receive the exposure over one hour, three times daily. The mother of each enrolled participant will be asked to read a short story selected by the research team, for ten minutes. This recording will be processed using a software program to convert the 10 minute reading into an mp3 recording which will automatically play the desired 'dose' throughout the day at three 1-hour intervals. A team of research nurses enrolled in the study will be responsible for pressing play on the recording in the morning.

Rossetti Infant-Toddler Language Scale (3 months)
The Rossetti Infant-Toddler Language Scale measures communication and interaction in infant at 3 months of age. It is used as a screening tool to identify infants at risk. The instrument assesses six components: Interaction-Attachment, Pragmatics, Gesture, Play, Language Comprehension, and Language Expression.

Prechtl general movements assessment (3 months)
The Prechtl assessment is used to assess absent or abnormal general movements of infants at 3 months of age. The assessment tool is widely used and there is substantial evidence that this method has good inter- and intra-observer agreement. The tool has been shown to be a good predictor of neurological outcome.

Intermediate outcomes [3, 6, 12 months]
Hammersmith Infant Neurological Examination [HINE] (3, 6 & 12 months)
HINE is a neurological examination that can be used to assess neurological ability of infants from 2-24 months of age. Twenty-six elements are included across five separate domains, which are combined to create a global score. The tool has been widely used in both term and preterm infants and has shown good predictability of Cerebral Palsy in scores less than 57 at 3 months of age (sensitivity 96% and specificity 87%).

Communication & Symbolic Behaviour Scales Developmental Profile [CSBS DP] (6 & 12 months)
Is a routine screening tool which is used to assess 6 main elements including: emotion and eye gaze, communication, gestures, infant sounds, infant words, and understanding. The results produce a dichotomous variable of either 'concern' or 'no concern' which is then used for early referral to the GCUH multi-disciplinary clinic for further follow-up.

Efficacy
Statistical methods / analysis
A sample size of 14 in each group was calculated using a power of 0.8 and a significance level of 0.05 for detecting an effect size of 1 standard deviation (SD) difference (15 points) on Bayley III Scales of Infant Development by means of a two-sample t-test. As it is likely that twins will be enrolled, the sample size estimate will be required to be inflated by a factor of 1+(m-1)r (the design effect) where m is the mean number of babies per mother and r is the intraclass correlation coefficient with respect to the outcome of interest. From previous studies (eg Gray PH, Pers. Comm.) we estimated m=1.19 and r to range from 0.58 to 0.69 for Bayley IV Cognitive, Language, and Motor scores thus, using r=0.69, giving an adjusted total sample size of 28×1.1311=32. As this is a longitudinal study with a two year follow up, an allowance of an attrition rate of 30% has further been calculated into the sample size. That is, sample size = 32/(1-0.3)=46, or 23 per group.
