Brief summary
The language environment that influences the child's language development has been studied using different subjective tools, mainly audio and/or video recording and manual transcriptions. The linguistic results of the implanted deaf child are dependent on the age at the implant, but also on the auditory and linguistic stimulation in the first months following the placement of the implant. Parents are the main actors in the child's language development. Professionals can rely on the LENA tool: Language ENvironment Analysis, which objectifies the language environment of the child at home in his daily environment. It is possible to obtain statistics on the number of adult words received by the child, the number of words produced by the child as well as the exposure to media and noise. On the basis of this quantitative data, the family can be supported in an attempt to optimize the conditions for receiving their child's speech. The purpose of this study is to analyze the effect of speech therapy parental support using the data provided by the Language ENvironment Analysis (LENA) tool, in a pediatric population implanted early, i.e. before the age of 18 months and aged under 24 months inclusive at the start of their participation in the study.
Detailed description
The language environment that influences the child's language development has been studied using different subjective tools, mainly audio and/or video recording and manual transcriptions.

Parents are the main actors in the child's language development. Professionals can rely on the LENA tool: Language ENvironment Analysis, which objectifies the language environment of the child at home in daily environment. On the basis of this quantitative data provided by the LENA, the family can be supported in an attempt to optimize the conditions for receiving their child's speech. The purpose of this study is to analyze the effect of speech therapy parental support using the data provided by the Language ENvironment Analysis (LENA) tool, in a pediatric population implanted early, i.e. before the age of 18 months and aged under 24 months inclusive at the start of their participation in the study. The LENA tool was validated in French version in 2015. It is a system of recording and automatic analysis of the language environment of the child using a box worn for 10-16 hours, with a minimum of 10 consecutive hours. For the study, the families make 2 separate recordings of 6 months at home (T1 and T2) then, a centralized analysis of all the data is carried out by the speech therapist using adapted software, the LENA Pro Version Software v3.4, during the times T1 and T2. The return of the analysis of the data collected via the LENA will be made to the family after T1 and after T2. The parameters resulting from this analysis relate to four domains: adult words, conversation turns, child vocalizations and exposure to electronic media. Average numerical scores expressed in percentiles are published at the end of the analysis. Individual scores are then compared to a standard expressed as percentiles. The content of the conversations will not be listened to and only numerical scores will be used for each of the parameters studied and obtained by computer analysis.
Interventions
OTHERLENA tool: Language ENvironment Analysis
Recording of the language environment of the child at home, in daily environment, with the LENA. The parameters recorded relate to four domains: adult words, conversation turns, child vocalizations and exposure to electronic media. The LENA box is worn for 10-16 hours, with a minimum of 10 consecutive hours. the families make 2 separate recordings of 6 months at T1 and T2.
BEHAVIORALReturn of the analysis of the data of LENA
The analysis of the LENA data is carried out by the speech therapist using the LENA Pro Version Software v3.4, during the times T1 and T2. The return of the analysis of the data collected via the LENA will be made to the family of the patient after T1 and after T2 and personalized advice will then be given to parents with the aim of improving their child's language skills.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of conversation turns | 6 months | Comparison of the variation in language environment for the number of conversation turns recorded at T1 and the number of conversation turns recorded at T2 after speech therapy support offered at T1 and based on data provided by the Language ENvironment Analysis (LENA) tool. Average numerical scores expressed in percentiles are produced at the end of the analysis. The individual scores are then compared with a standard expressed in percentiles. |
| Receptive lexical level | 6 months | Receptive lexical level measured by the speech therapy test (IFDC, French inventories of Communicative Development) at T1 and T2. Each child's individual result is given in percentiles according to chronological age. It is based on an evaluation sheet with benchmarks in percentiles (10th to 90th) or percentages. |
| Correlation between the number of conversation turns parameter and the receptive lexical level | 6 months | The correlation between the conversation turns parameter recorded at T1 and T2 and the receptive lexical level measured by the speech therapy test (IFDC, French inventories of Communicative Development) at T1 and T2 will be carried out. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Link between 3 language environment parameters: adult words, child vocalization, exposure to electronic media and the receptive lexical level | 6 months | To study the link between the 3 others language environment parameters (adult words, child vocalization, exposure to electronic media), evaluated by the LENA system and the receptive lexical level, measured by the standardized speech therapy test carried out at T1 and T2. Average numerical scores expressed in percentiles are produced at the end of the analysis. The individual scores are then compared with a standard expressed in percentiles. |
| Family participation during speech therapy | 6 months | Comparison of scores from the family participation scale at T1 and T2. The speech and language therapist subjectively assesses the family's involvement by assigning a number corresponding to the level of involvement and motivation: the calibration is made from 1 (limited involvement) to 5 (ideal involvement). |
| Acceptability of the use of the LENA tool for children under 3 years | 24 months | Evaluate the acceptability of the use of the LENA tool for children under 3 years old implanted between 8 and 18 months using the acceptability questionnaire completed by the parents concerning the use of the LENA system in their child at T1 and T2. An acceptability score will be calculated on the basis of this questionnaire and expressed as a percentage: the questionnaire consists of 6 questions, each answer worth 2, 1 or 0 points (i.e. a maximum gross score of 12 points), then the gross score divided by 6 and multiplied by 50 to obtain a percentage score (100% corresponding to excellent acceptability). |
| Protocolizing the individual strategies given to help and support parents to enrich their child's language environment | 6 months | Analyze the individual results obtained from the language environment data collected from the LENA tool, in order to provide personalized advice to parents after T1 and T2, with the aim of improving their child's language environment. Comparison of individual scores at T1 and T2 for the 4 parameters evaluated by the LENA system (adult words, conversation turns, child vocalizations and exposure to electronic media) with the means scores obtained. Carry out a process of protocolizing the individual strategies given to help and support parents in enriching their child's language environment. |
