SYSTEM REQUIREMENTS:
FUNCTIONAL REQUIREMENTS:
Helpful requirement specifies what Alexa system ought to do. It moreover describes the efficiency and suppliers provided by the it. It would comprise calculation, technical particulars ,information manipulation and processing and the efficiency that the software program program must get hold of.
1. Physique alerts or gestures ought for use to activate./off the lamps and music methods
2. Alexa ought to be succesful to be accessed by the use of quite a few mobile phone models
three. Alexa must be succesful to current compulsory ideas information, in human language
4. The ideas information that the system provides might be whether or not or not the system recognises the right information and executes correct actions.
5. It ought to moreover current button choices as some prospects select to utilize it over speech.
6. Alexa additionally must allow to handle the home models when the buyer is way away from residence
7. Most basic and needed attribute that it must current is to activate/off music stereo and residential lamps by the use of voice.
eight. It must be succesful so as to add or take away new models into the system.
NON FUNCTIONAL REQUIREMENTS:
Accessibility :Accessibility is the diploma to which a service, gadget or setting is obtainable. Alexa must be merely accessible to quite a few people and models and ought to be merely understandable by the highest prospects and prospects.
Usability :As Alexa makes use of a voice recognition primarily based system,there is also points with some voice with accent. It ought to nonetheless accept the language and execute the obligatory instruction. If the system cannot acknowledge the shoppers command, it must counsel to the buyer about related selections primarily based totally on the command. It additionally must be managed by the use of buttons and by no means solely voice primarily based instructions.
Reliability :Reliability emphasizes dependability throughout the lifecycle administration of a product. Dependability, or specified time interval. The throughout the Alexa must be safe adequate to handle the switches of digital equipments. Moreover a shopper must be succesful to look at the entire command has been made and the system ought to keep up monitoring prospects directions.The log helps shopper and the system to understand the shoppers habits greater and improve the usual of voice recognition by predicate prospects directions. Effectivity :Effectivity is characterised by the useful work accomplished by a system compared with the time and belongings used. A shopper must get ideas in a extremely temporary time after he offers the directions. The processing time must be temporary and ought to have the ability to performing sophisticated calculations.
ARCHITECTURAL DESIGN:
The architectural design for voice managed Residence Automation using Alexa embody a microcontroller comparable to an arduino, Amazon Web Corporations ,relays and models associated by means of quite a few and protocols.

Architectural design for voice managed residence automation system using AlexaThe Alexa voice service is a part of Amazon Web Corporations. This consists of an alexa app which will be a part of alexa enabled gadget like amazon echo. The app calls up a dialogue the place the buyer logs in and selects the arrange he needs to handle with Alexa comparable to cameras, tV, lights, and so forth. The models are associated by means of quite a few interfaces and protocols.
Architectural pattern:
The system can have a layered construction, Shopper and server construction, database construction, event pushed construction.
Layered construction:
Establish: Layered construction
Description: The system is organised into 4 layers primarily based totally on the efficiency associated to each layer. The suppliers offered by the lower layers such as a result of the models like sensors are utilized by the layer about it comparable to gadget supervisor, gateway for communication to happen.
When used: The layer is used for multilevel security by providing choices comparable to login, authorisation, and so forth.
Advantages: Shopper authentication might be provided enhance the dependability of the system.
Disadvantages: Failure of 1 layer in a interferes with the functioning off the layers above, as information cannot be accessed from lower layers, like information from the sensors cannot be retrieved by the servers to course of the information.
The layer construction of this system consists of the first layers :The bodily layer contains of the models, comparable to, lights, digital digital camera ,TV, soundbar ,and so forth.
The information hyperlink layer consists of gateway, communication protocols, gadget supervisor ,and so forth.
The neighborhood and transport layer consists of the online or servers
usually for authentication or authorisation.
The topmost layer consists of web portals, cell functions( shopper interfaces).

Shopper-Server construction:
Establish: Shopper server construction
Description: The system is organised into suppliers with each service delivered from a separate server.
When used: This construction permits completely completely different consumers to handle the by the use of authorising and determining them.
Advantages: Corporations might be accessed by the patrons to servers distributed all through a neighborhood and wait until the buyer receives a reply.
Downside: Service might be denied as each service is a single degree of failure.
