Projets-2015-2016-Borne-Interactive-SRS

=1.  Introduction=

1.1 Purpose of the requirements document
This Software Requirements Specification (SRS) identifies the requirements for project "Borne Interactive". In case of a open source project, we must present the requirement to others potential contributors. This document is a guideline about the functionalities offered and the problems that the system solves.

1.2 Scope of the product
Intended for any organization wishing to facilitate the reception of hearing impaired people. The goal is not to substitute the original speech but improve it, and it doesn't provide any way to answer back.

1.3 Definitions, acronyms and abbreviations

 * "Borne Interactive" : Interactive display on two screens or two interfaces : one for the speaker and one for the listener.


 * API : Application Programming Interface.


 * Google Chrome : The main browser used to run the display.

1.5 Overview of the remainder of the document
General desccription of the project followed by all its requirements and the product evolution.

=2.  General description= The aim of this project is to design a new interactive system to help impaired hearing people, by writing what the receptionnist is saying.

2.1 Product perspective
When deaf(or impaired hearing) people come at a reception stand, to request informations for example, they can have difficulties to understand the receptionist. Our product intends to make a live transcription of the receptionist speech and write it down on a screen. The person understands the receptionist in a better way, especially in a noisy environnment where it's hard to communicate. Since voice recognition make mistakes and doesn't recognise technical terms, our product also a mean of correction for the receptionist.

2.2 Product functions
Live transcription of the receptionist voice. Possibility to correct the transcription (for mistakes or technical terms).

2.3 User characteristics
Two types of users, the receptionist and the deaf (or impaired hearing) person. The receptionist can correct the live transcription via his interface. The impaired hearing person read the live transcription in an easy way.

2.4 General constraints
Only made by using Web technologies such as HTML/PHP/JavaScript to make it run on almost every device. Must use the Google Speech Recognition.

2.5 Assumptions and dependencies
=3.Specific requirements, covering functional, non-functional and interface requirements=
 * document external interfaces,
 * describe system functionality and performance
 * specify logical database requirements,
 * design constraints,
 * emergent system properties and quality characteristics.

3.1 Requirement X.Y.Z (in Structured Natural Language)
Function:Live transcription

Description: When the receptionist speak a live transcription can be seen by both users.

Inputs: Voice command or button press to start the transcription.

Source: Mouse or microphone.
