Projets-2015-2016-Borne-Interactive-SRS

=1.  Introduction=

1.1 Purpose of the requirements document
This Software Requirements Specification (SRS) identifies the requirements for the 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. It's a set of routines, protocols, and tools for building software and applications generally focused on certain tasks like extracting information about specific data or in our case to have access to speech recognition methods.


 * Google Speech API : The API made by Google to implement speech recognition in our application.


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

1.5 Overview of the remainder of the document
General description 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. It can also help people with concentration problems by providing a way to keep track of the conversation.

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 offer a mean of correction for the receptionist. It can also be used to help people with concentration issues who can have troubles keeping track of a conversation.

2.2 Product functions
Live transcription of the receptionist voice. Possibilities:
 * Correcting the transcription (for mistakes or technical terms).
 * Conversation history can be printed.
 * Simple formatting with buttons

2.3 User characteristics
Two types of users, the receptionist and the impaired hearing person (or deaf, or with concentration issues). The receptionist can correct the live transcription via his interface. He can print the transcript of the transcription. 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. It must use the Google Speech Recognition API in order to see its limitations and possibilities.

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.

Network constraint: To use the application an internet connection fast enough to handle the Google API is necessary. It's the only thing that conenct to the internet. The rest is stricly local. System requirement: The application can run on all device capable of handling a modern browser, at least two tabs and of course a internet connection.

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.

Outputs: Screen (Touchscreen?)

Destination: This device is designed to used in a reception environment susceptible of welcoming deaf (or impaired) people.(University, Post office...)

Action:
 * Natural language sentences (with MUST, MAY, SHALL)
 * Graphical Notations : UML Sequence w/o collaboration diagrams, Process maps, Task Analysis (HTA, CTT)
 * Mathematical Notations
 * Tabular notations for several (condition --> action) tuples

Non functional requirements:
