You’ve doubtless skilled the problem of taking notes throughout a gathering whereas making an attempt to concentrate to the dialog. You’ve in all probability additionally skilled the necessity to shortly fact-check one thing that’s been mentioned, or lookup data to reply a query that’s simply been requested within the name. Or perhaps you’ve got a crew member that at all times joins conferences late, and expects you to ship them a fast abstract over chat to catch them up.
Then there are the instances that others are speaking in a language that’s not your first language, and also you’d like to have a dwell translation of what persons are saying to be sure to perceive accurately.
And after the decision is over, you normally need to seize a abstract to your information, or to ship to the individuals, with an inventory of all of the motion gadgets, house owners, and due dates.
All of this, and extra, is now attainable with our latest pattern resolution, Reside Assembly Assistant (LMA).
Try the next demo to see the way it works.
On this publish, we present you the best way to use LMA with Amazon Transcribe, Amazon Bedrock, and Data Bases for Amazon Bedrock.
Answer overview
The LMA pattern resolution captures speaker audio and metadata out of your browser-based assembly app (as of this writing, Zoom and Chime are supported), or audio solely from every other browser-based assembly app, softphone, or audio supply. It makes use of Amazon Transcribe for speech to textual content, Data Bases for Amazon Bedrock for contextual queries in opposition to your organization’s paperwork and information sources, and Amazon Bedrock fashions for customizable transcription insights and summaries.
The whole lot you want is offered as open supply in our GitHub repo. It’s simple to deploy in your AWS account. If you’re performed, you’ll marvel the way you ever managed with out it!
The next are a number of the issues LMA can do:
- Reside transcription with speaker attribution – LMA is powered by Amazon Transcribe ASR fashions for low-latency, high-accuracy speech to textual content. You may educate it model names and domain-specific terminology if wanted, utilizing customized vocabulary and customized language mannequin options in Amazon Transcribe.
- Reside translation – It makes use of Amazon Translate to optionally present every section of the dialog translated into your language of alternative, from a number of 75 languages.
- Context-aware assembly assistant – It makes use of Data Bases for Amazon Bedrock to offer solutions out of your trusted sources, utilizing the dwell transcript as context for fact-checking and follow-up questions. To activate the assistant, simply say “Okay, Assistant,” select the ASK ASSISTANT! button, or enter your personal query within the UI.
- On-demand summaries of the assembly – With the clicking of a button on the UI, you may generate a abstract, which is beneficial when somebody joins late and must get caught up. The summaries are generated from the transcript by Amazon Bedrock. LMA additionally supplies choices for figuring out the present assembly matter, and for producing an inventory of motion gadgets with house owners and due dates. You can even create your personal customized prompts and corresponding choices.
- Automated abstract and insights – When the assembly has ended, LMA robotically runs a set of huge language mannequin (LLM) prompts on Amazon Bedrock to summarize the assembly transcript and extract insights. You may customise these prompts as effectively.
- Assembly recording – The audio is (optionally) saved for you, so you may replay essential sections on the assembly later.
- Stock record of conferences – LMA retains monitor of all of your conferences in a searchable record.
- Browser extension captures audio and assembly metadata from standard assembly apps – The browser extension captures assembly metadata—the assembly title and names of energetic audio system—and audio from you (your microphone) and others (from the assembly browser tab). As of this writing, LMA helps Chrome for the browser extension, and Zoom and Chime for assembly apps (with Groups and WebEx coming quickly). Standalone assembly apps don’t work with LMA —as a substitute, launch your conferences within the browser.
You might be chargeable for complying with authorized, company, and moral restrictions that apply to recording conferences and calls. Don’t use this resolution to stream, document, or transcribe calls if in any other case prohibited.

At all times receive permission from others earlier than recording them utilizing LMA, or every other recording software.
Processing move overview
How did LMA transcribe and analyze your assembly? Let’s take a look at the way it works. The next diagram reveals the primary architectural elements and the way they match collectively at a excessive degree.
The LMA consumer joins a gathering of their browser, permits the LMA browser extension, and authenticates utilizing their LMA credentials. If the assembly app (for instance, Zoom.us) is supported by the LMA extension, the consumer’s title, assembly title, and energetic speaker names are robotically detected by the extension. If the assembly app will not be supported by the extension, then the LMA consumer can manually enter their title and the assembly matter—energetic audio system’ names is not going to be detected.
After getting permission from different individuals, the LMA consumer chooses Begin Listening on the LMA extension pane. A safe WebSocket connection is established to the preconfigured LMA stack WebSocket URL, and the consumer’s authentication token is validated. The LMA browser extension sends a START message to the WebSocket containing the assembly metadata (title, matter, and so forth), and begins streaming two-channel audio from the consumer’s microphone and the incoming audio channel containing the voices of the opposite assembly individuals. The extension displays the assembly app to detect energetic speaker adjustments in the course of the name, and sends that metadata to the WebSocket, enabling LMA to label speech segments with the speaker’s title.
The WebSocket server operating in Fargate consumes the real-time two-channel audio fragments from the incoming WebSocket stream. The audio is streamed to Amazon Transcribe, and the transcription outcomes are written in actual time to Kinesis Knowledge Streams.
Every assembly processing session runs till the consumer chooses Cease Listening within the LMA extension pane, or ends the assembly and closes the tab. On the finish of the decision, the operate creates a stereo recording file in Amazon S3 (if recording was enabled when the stack was deployed).
A Lambda operate known as the Name Occasion Processor, fed by Kinesis Knowledge Streams, processes and optionally enriches assembly metadata and transcription segments. The Name Occasion Processor integrates with the assembly help providers. LMA is powered by Amazon Lex, Data Bases for Amazon Bedrock, and Amazon Bedrock LLMs utilizing the open supply QnABot on AWS resolution for solutions based mostly on FAQs and as an orchestrator for request routing to the suitable AI service. The Name Occasion Processor additionally invokes the Transcript Summarization Lambda operate when the decision ends, to generate a abstract of the decision from the total transcript.
The Name Occasion Processor operate interfaces with AWS AppSync to persist adjustments (mutations) in Amazon DynamoDB and ship real-time updates to the LMA consumer’s logged-in internet purchasers (conveniently opened by selecting the Open in LMA possibility within the browser extension).
The LMA internet UI property are hosted on Amazon S3 and served by way of CloudFront. Authentication is offered by Amazon Cognito.
When the consumer is authenticated, the online software establishes a safe GraphQL connection to the AWS AppSync API, and subscribes to obtain real-time occasions akin to new calls and name standing adjustments for the conferences record web page, and new or up to date transcription segments and computed analytics for the assembly particulars web page. When translation is enabled, the online software additionally interacts securely with Amazon Translate to translate the assembly transcription into the chosen language.
Your complete processing move, from ingested speech to dwell webpage updates, is occasion pushed, and the end-to-end latency is brief—usually only a few seconds.
Monitoring and troubleshooting
AWS CloudFormation reviews deployment failures and causes on the related stack’s Occasions tab. See Troubleshooting CloudFormation for assist with frequent deployment issues. Look out for deployment failures brought on by restrict exceeded errors; the LMA stacks create assets which are topic to default account and Area service quotas, akin to elastic IP addresses and NAT gateways. When troubleshooting CloudFormation stack failures, at all times navigate into any failed nested stacks to seek out the primary nested useful resource failure reported—that is nearly at all times the basis trigger.
Amazon Transcribe has a default restrict of 25 concurrent transcription streams, which limits LMA to 25 concurrent conferences in a given AWS account or Area. Request a rise for the variety of concurrent HTTP/2 streams for streaming transcription in case you have many customers and must deal with a bigger variety of concurrent conferences in your account.
LMA supplies runtime monitoring and logs for every element utilizing CloudWatch:
- WebSocket processing and transcribing Fargate activity – On the Amazon Elastic Container Service (Amazon ECS) console, navigate to the Clusters web page and open the LMA-
WEBSOCKETSTACK-xxxx-TranscribingCluster
operate. Select the Duties tab and open the duty web page. Select Logs and View in CloudWatch to examine the WebSocket transcriber activity logs. - Name Occasion Processor Lambda operate – On the Lambda console, open the
