Communication difficulties associated with cerebral palsy can be multifactorial, arising from motor, intellectual and / or sensory impairments. Affected children can experience mild to severe difficulties in expression. Those with little or no functional speech frequently rely on non-speech communication systems to augment or replace natural speech. These systems include speech generating devices (SGDs). AVAZ is a portable speech synthesizer which can be controlled by the gross motor movements of a child with cerebral palsy.
This case study describes the outcomes of a pilot investigation that utilised AVAZ as a means of enhancing functional communication in a young girl with cerebral palsy.
A 7-year-old girl with cerebral palsy and complex communication needs was trained for 10 sessions to develop requesting ability by pointing to the desired pictures on the AVAZ.
After the training sessions, the child showed improvement in social interaction and functional communication.Conclusions and Implication: The collaborative efforts of an inter-disciplinary team, comprising a speech pathologist, a physiotherapist, parents of the child and a social worker, made it possible to enhance the child’s confidence and functional communication using AVAZ.Hence it is important to pursue client-oriented, innovative and collaborative intervention approaches among team members.Key words: Cerebral palsy, complex communication need, speech generating device, functional communication.

2. iPad: efficacy of electronic devices to help children with autism spectrum disorder to communicate in the classroom
- By Sulata Ajit, Sankalp school, Chennai (2017)
Children with Autism Spectrum Disorder (ASD) are known to have difficulty in social communication, with research indicating that children with ASD fail to develop functional speech (Lord and Rutter, 1994). Over the years a number of Augmented and Alternate Communication (AAC) devices have been used with children with ASD to overcome this barrier and to facilitate communication. This article examines an Indian AAC tool called AVAZ (meaning sound), which is the first of its kind in India. The project reported also looks at the effectiveness of using AVAZ and the use of iPads by children with ASD in the classroom. Additionally, the article examines the suitability of using iPads for all learners in the spectrum. Twenty children between the ages of 4 and 10 years were selected to trial the use of AVAZ. They received three sessions weekly of 45 minutes over a period of 10 weeks. The feedback of the special educators who trained the children was analysed. The findings of this small scale study indicates that the children preferred using the AVAZ app and the iPad to pen and paper. Huguenin (2004) too indicated similar reports in using Information and Communication Technology (ICT) in enhancing children's motivation to learn and communicate. The trainers felt it could be used as an educational tool, and many more educational concepts could be added. Research also suggests that ICT can be used as a tool to tutor for educational purpose (Means, 1994). The AVAZ app could be recommended to children with ASD who are included in mainstream schools. This study was conducted at Sankalp, a special school in Tamil Nadu, Chennai.

Background: Children with autism spectrum disorder (ASD) who are nonverbal lack communication skills. These children with ASD are unable to express their needs verbally even if they want to. The introduction of indigenous augmentative and alternative communication system (AAC) can be helpful in improving the social interaction. By using AAC, these children with ASD can easily communicate their needs with parents, teachers, or caregivers. Objective: The objective of this study is to evaluate the importance and need of AVAZ application in special school-going children with ASD. Study Design: A pilot study for short term on small sample was conducted. Methods: A sample of eight special school-going children with ASD was selected. Each child had downloaded AVAZ application trial version on their smartphone from the Google Play Store. The number of sentences formed by the children over a period of 21 days was analyzed. The responses were recorded in the AVAZ application. Results: Percentage improvement was noted in forming relevant sentences through the application of each child from the 1st to 21st session ranging from 28.5% to 40%; five children showed the improvement but three children did not form any sentence neither relevant nor nonrelevant. Conclusion: Our study showed that the use of AVAZ application can be helpful in improving social interaction and can be utilized as a supporting tool for functional communication with others and for the better learning process in children with ASD.

Aphasia is an impairment of language that is a consequence of a cerebral insult or damage affecting
the speech production and/or comprehension, as well as the ability to read or write. Etiology of
Aphasia is multifactorial, most commonly in the form of a stroke (Cerebrovascular Accident),
especially in older individuals. The type of aphasia is determined based on multiple factors such as the
site of lesion, signs and symptoms and also through patient’s clinical presentation. Rehabilitation for
stroke survivors plays a major role in communication effectiveness. Computerized Intervention
method provides a prognostic factor in the treatment for adults with aphasia. AAC devices (high-tech)
are used to enhance communicative effectiveness of aphasic individuals who are less likely to use
strategies/techniques that the caregiver can use to foster interactions between themselves and the
aphasic individual outside the treatment setting. Other factors that determine the success of the
intervention are the intensiveness and the duration of intervention. This study focuses on one such
intervention of an adult Anomic Aphasia patient using a high tech AAC computerized application
known as Avaz. The results showed that the client was able to perform much better in terms of the
word retrieving abilities and is now able to communicate well.

7. Capitalizing on technology for developing communication skills in autism spectrum disorder: a single case study
- By Veena Mohan, Suja Kurian Kunnath, Vineetha Sara Philip, Lakshmi Santha Mohan & Neethu Thampi (2017)
Purpose: In this case study, we discuss the application of a patient-centred clinical approach that led to the use of an assisted communication platform to combat severe communicative deficit in a child with autism spectrum disorder (ASD).
Methods: Initial assessment at four years of age revealed that the patient had rudimentary communication skills, with significant sensory integration dysfunction manifested as oral, olfactory, and tactile seeking behaviours; self-stimulatory behaviour; and complete dependence on caregiver for activities of daily living. Intensive, multi-disciplinary intervention resulted in minimal improvement in communicative skills and sensory seeking over six months. Subsequently, a tailor-made picture-assisted communication training with the mother as the communication facilitator was adopted. This approach was abandoned due to the patient's poor response and mother's low acceptance of picture-based interaction. A preference for printed material was observed in the patient. Accordingly, further management was focused on employing a computer-based interactive platform that the patient was taught to use over the course of a few months as a part of augmentative and alternative communication (AAC) intervention program. This resulted in a remarkable improvement in the child's skills that now allowed for a better intentional communication of his thoughts and needs.
Conclusions: This study highlights the importance of revisiting conventional rehabilitation strategies for communicative deficits and tailoring them according to the patient's needs and preferences. It also emphasises that besides excellent observation skills, clinicians must be willing to consider technology based approaches in patients responding poorly to traditional approaches in order to develop effective interventional programmes. Implication for Rehabilitation The current study highlights the importance of exploring the application of technology based intervention for building communication skills in the early stages of rehabilitation for persons with communicative deficit. It also emphasises the need for excellent observation skills among clinicians so that the peculiar interests of children with ASD may be applied in designing training programmes to overcome communication barriers. Additionally, clinicians should familiarise themselves with the latest assistive technology-based rehabilitation approaches and be willing to explore newer approaches if traditional ones fail to yield satisfactory outcomes. Use of technology-based interventions to reduce dependence among persons with disability would be beneficial, both socially and economically, in developing countries with limited resources.
