It will be used in project to listen voice of customer to make voice commands and reproduce sentence by human voice. Testing criteria:

• Relevance
• Timbre of voice
• API functionality
• Free period of use
• Ability to reproduce and listen at the same time

The layout of the first page of the application implies the addition of a separate page on Flutter with the possibility of further adding the functionality of parsers

Development of accompanying documentation, which should contain:

1. Description of the application functionality
2. Used technologies
3. Description of the main points of implementation
4. Deployment Instructions
5. Additional information required by the customer.

The animation of the second page shows the user the change of tokens visually. The current token should be in the center and stand out. It is also worth showing the next and previous ones, but focusing less on them with the help of dimmer colors and smaller sizes.

At this stage, an existing API is being integrated into the application functionality. Start button - starts the memorization process Play button - starts the voice track Stop button - stops it Previous button - returns to the previous token Next button - leads to the next token

Now it is necessary to implement separately developed functionality into the created application skeleton: a parser and a tokenizer. At the same time, the development of the general functionality of the first page is being completed.

At this stage, a single application structure is being formed, so it is necessary:

1. Assemble a common project in which to create the final application
2. Add the created pages to it, and then create a link between them through the simplest functionality

At the same time, it is important to achieve hierarchy: we should not see the second page until the functionality finishes processing on the first one. Instead of the functionality, you should put a plug on the first one for now.

The layout of the second page implies the implementation of the entire UI of the second page application separately, followed by the possibility of integrating the API with voice recognition and playback. At the same time, it is not necessary to implement the functionality of the buttons at this stage, this is a preparatory base.

Architecture development includes the development of system objects and their interaction with each other. At the same time, it is necessary to put elasticity into the system for possible edits of the customer.

It is necessary to set up a meeting with the customer, record it and its main changes regarding the documentation, in order to then correct it with the team.

Project testing includes both using the project and deploying it on various devices to test adaptability. At the same time, it is necessary to use stress testing to check the behavior of the system in extreme situations.

During the memorization process, there may be conflicts in words. For example, the user can say stop, and then playback stops. However, the word stop may appear in the text, then the system will react to it. It is necessary to learn how to handle such conflicts. Either from a technical point of view, or by introducing some restrictions for the user.

Integration of voice control for the user. As a result, the user will be able to control the memorization process without using the function buttons on the second page. That is, it is necessary to duplicate the functionality for each button.
