2. The consumer indicators in by getting into a consumer identify and a password. Authentication is carried out in opposition to the Amazon Cognito consumer pool. After a profitable login, the Amazon Cognito id pool is used to supply the consumer with the short-term AWS credentials required to entry utility options. For extra particulars in regards to the authentication and authorization flows, discuss with Accessing AWS services using an identity pool after sign-in.
3. The extension interacts with Amazon Transcribe (StartStreamTranscription operation), Amazon Translate (TranslateText operation), and Amazon Bedrock (InvokeModel operation). Interactions with Amazon Bedrock are dealt with by a Lambda perform, which implements the appliance logic underlying an API made accessible utilizing API Gateway.
4. The consumer is supplied with the transcription, translation, and abstract of the content material enjoying contained in the browser tab. The abstract is saved inside an S3 bucket, which could be emptied utilizing the extension’s Clear Up function.

Within the following sections, we stroll by tips on how to deploy the Chrome extension and the underlying backend assets and arrange the extension, then we show utilizing the extension in a pattern use case.

Stipulations

For this walkthrough, you must have the next stipulations:

Deploy the backend

Step one consists of deploying an AWS Cloud Development Kit (AWS CDK) utility that robotically provisions and configures the required AWS assets, together with:

• An Amazon Cognito user pool and identity pool that enable consumer authentication
• An S3 bucket, the place transcription summaries are saved
• Lambda capabilities that work together with Amazon Bedrock to carry out content material summarization
• IAM roles which can be related to the id pool and have permissions required to entry AWS companies

Full the next steps to deploy the AWS CDK utility:

1. Utilizing a command line interface (Linux shell, macOS Terminal, Home windows command immediate or PowerShell), clone the GitHub repository to an area listing, then open the listing:

git clone https://github.com/aws-samples/aws-transcribe-translate-summarize-live-streams-in-browser.git
cd aws-transcribe-translate-summarize-live-streams-in-browser

2. Open the cdk/bin/config.json file and populate the next configuration variables:

{
    "prefix": "aaa123",
    "aws_region": "us-west-2",
    "bedrock_region": "us-west-2",
    "bucket_name": "summarization-test",
    "bedrock_model_id": "anthropic.claude-3-sonnet-20240229-v1:0"
}

The template launches within the us-east-2 AWS Area by default. To launch the answer in a special Area, change the aws_region parameter accordingly. Ensure that to pick a Area through which all of the AWS companies in scope (Amazon Transcribe, Amazon Translate, Amazon Bedrock, Amazon Cognito, API Gateway, Lambda, Amazon S3) are available.

The Area used for bedrock_region could be totally different from aws_region since you might need entry to Amazon Bedrock fashions in a Area totally different from the Area the place you wish to deploy the venture.

By default, the venture makes use of Anthropic’s Claude 3 Sonnet as a summarization mannequin; nevertheless, you should use a special mannequin by altering the bedrock_model_id within the configuration file. For the entire checklist of mannequin IDs, see Amazon Bedrock model IDs. When choosing a mannequin on your deployment, don’t overlook to examine that the specified mannequin is offered in your most popular Area; for extra particulars about mannequin availability, see Model support by AWS Region.

3. You probably have by no means used the AWS CDK on this account and Area mixture, you’ll need to run the next command to bootstrap the AWS CDK on the goal account and Area (in any other case, you may skip this step):

npx cdk bootstrap aws://{targetAccountId}/{targetRegion}

4. Navigate to the cdk sub-directory, set up dependencies, and deploy the stack by operating the next instructions:

cd cdk
npm i
npx cdk deploy

5. Verify the deployment of the listed assets by getting into y.

Look forward to AWS CloudFormation to complete the stack creation.

It is advisable use the CloudFormation stack outputs to attach the frontend to the backend. After the deployment is full, you’ve two choices.

The popular choice is to make use of the supplied postdeploy.sh script to robotically copy the cdk configuration parameters to a configuration file by operating the next command, nonetheless within the /cdk folder:

Alternatively, you may copy the configuration manually:

1. Open the AWS CloudFormation console in the identical Area the place you deployed the assets.
2. Discover the stack named AwsStreamAnalysisStack.
3. On the Outputs tab, notice of the output values to finish the subsequent steps.

Arrange the extension

Full the next steps to get the extension prepared for transcribing, translating, and summarizing reside streams:

1. Open the src/config.js Primarily based on the way you selected to gather the CloudFormation stack outputs, observe the suitable step:
   1. When you used the supplied automation, examine whether or not the values contained in the src/config.js file have been robotically up to date with the corresponding values.
   2. When you copied the configuration manually, populate the src/config.js file with the values you famous. Use the next format:

const config = {
    "aws_project_region": "{aws_region}", // The identical you've used as aws_region in cdk/bin/config.json
    "aws_cognito_identity_pool_id": "{CognitoIdentityPoolId}", // From CloudFormation outputs
    "aws_user_pools_id": "{CognitoUserPoolId}", // From CloudFormation outputs
    "aws_user_pools_web_client_id": "{CognitoUserPoolClientId}", // From CloudFormation outputs
    "bucket_s3": "{BucketS3Name}", // From CloudFormation outputs
    "bedrock_region": "{bedrock_region}", // The identical you've used as bedrock_region in cdk/bin/config.json
    "api_gateway_id": "{APIGatewayId}" // From CloudFormation outputs
};

Pay attention to the CognitoUserPoolId, which can be wanted in a later step to create a brand new consumer.

2. Within the command line interface, transfer again to the aws-transcribe-translate-summarize-live-streams-in-browser listing with a command just like following:

cd ~/aws-transcribe-translate-summarize-live-streams-in-browser

3. Set up dependencies and construct the bundle by operating the next instructions:

4. Open your Chrome browser and navigate to chrome://extensions/.

Ensure that developer mode is enabled by toggling the icon on the highest proper nook of the web page.

5. Select Load unpacked and add the construct listing, which could be discovered contained in the native venture folder aws-transcribe-translate-summarize-live-streams-in-browser.
6. Grant permissions to your browser to file your display and audio:
   1. Establish the newly added Transcribe, translate and summarize reside streams (powered by AWS)
   2. Select Particulars after which Web site Settings.
   3. Within the Microphone part, select Permit.
7. Create a brand new Amazon Cognito consumer:
   1. On the Amazon Cognito console, select Consumer swimming pools within the navigation pane.
   2. Select the consumer pool with the CognitoUserPoolId worth famous from the CloudFormation stack outputs.
   3. On the Customers tab, select Create consumer and configure this consumer’s verification and sign-in choices.

See a walkthrough of Steps 4-6 within the animated picture under. For extra particulars, discuss with Creating a new user in the AWS Management Console.

Use the extension

Now that the extension in arrange, you may work together with it by finishing these steps:

1. On the browser tab, select the Extensions.
2. Select (right-click) on the Transcribe, translate and summarize reside streams (powered by AWS) extension and select Open aspect panel.
3. Log in utilizing the credentials created within the Amazon Cognito consumer pool from the earlier step.
4. Shut the aspect panel.

You’re now able to experiment with the extension.

5. Open a brand new tab within the browser, navigate to an internet site that includes an audio/video stream, and open the extension (select the Extensions icon, then select the choice menu (three dots) subsequent to AWS transcribe, translate, and summarize, and select Open aspect panel).
6. Use the Settings pane to replace the settings of the appliance:
   • Mic in use – The Mic not in use setting is used to file solely the audio of the browser tab for a reside video streaming. Mic in use is used for a real-time assembly the place your microphone is recorded as properly.
   • Transcription language – That is the language of the reside stream to be recorded (set to auto to permit automated identification of the language).
   • Translation language – That is the language through which the reside stream can be translated and the abstract can be printed. After you select the interpretation language and begin the recording, you may’t change your selection for the continued reside stream. To vary the interpretation language for the transcript and abstract, you’ll have to file it from scratch.
7. Select Begin recording to start out recording, and begin exploring the Transcription and Translation

Content material on the Translation tab will seem with a number of seconds of delay in comparison with what you see on the Transcription tab. When transcribing speech in actual time, Amazon Transcribe incrementally returns a stream of partial outcomes till it generates the ultimate transcription for a speech section. This Chrome extension has been carried out to translate textual content solely after a last transcription result’s returned.

8. Increase the Abstract part and select Get abstract to generate a abstract. The operation will take a number of seconds.
9. Select Cease recording to cease recording.
10. Select Clear all conversations within the Clear Up part to delete the abstract of the reside stream from the S3 bucket.

See the extension in motion within the video under.

Troubleshooting

When you obtain the error “Extension has not been invoked for the present web page (see activeTab permission). Chrome pages can’t be captured.”, examine the next:

• Ensure you’re utilizing the extension on the tab the place you first opened the aspect pane. If you wish to apply it to a special tab, cease the extension, shut the aspect pane, and select the extension icon once more to run it
• Ensure you have given permissions for audio recording within the net browser.

When you can’t get the abstract of the reside stream, ensure you have stopped the recording after which request the abstract. You possibly can’t change the language of the transcript and abstract after the recording has began, so bear in mind to decide on it appropriately earlier than you begin the recording.

Clear up

While you’re finished together with your exams, to keep away from incurring future expenses, delete the assets created throughout this walkthrough by deleting the CloudFormation stack:

1. On the AWS CloudFormation console, select Stacks within the navigation pane.
2. Select the stack AwsStreamAnalysisStack.
3. Pay attention to the CognitoUserPoolId and CognitoIdentityPoolId values among the many CloudFormation stack outputs, which can be wanted within the following step.
4. Select Delete stack and ensure deletion when prompted.

As a result of the Amazon Cognito assets received’t be robotically deleted, delete them manually:

5. On the Amazon Cognito console, find the CognitoUserPoolId and CognitoIdentityPoolId values beforehand retrieved within the CloudFormation stack outputs.
6. Choose each assets and select Delete.
