Demo

Use our API playground to visually build an api call. Use your choice of providers and couple them with NLP & NLU tasks.

ℹ️ Release Schedule: This repo will house all the connection adapters. We're set to release our code before end of Q1 2023 under the Apache License 2.0. For early access, email us at hello@exemplary.ai

At exemplary.ai, we're on a mission to help developers build Conversational AI apps faster, leverage advances in language technology, with the help of our API & Toolkit.

• Multi Provider flexibility. Quickly and easily compare, switch between, and try out different STT and NLP providers.
• No vendor lock-in Our provider agnostic format for transcript and transcript metadata storage allows you to build without worrying about provider specific workflows and implementation details.
• Use the best technology for the job Whether mitigating downtime, or benchmarking accuracy, with this API, leveraging the strengths of different providers is now easy. Try out new models and keep up to date on new features from different providers.
• Effortless ML pipelines for anyone Pipeline ASR and NLP tasks by simply stating the tasks you want, and the API will stitch them together while abstracting away provider specific job handling and callback mechanisms.
• Standardized transcript formats An open, standardized format, with adapters built for each provider, keeps this API maintainable and extensible. Easily add new Providers and functionality that integrates nicely with the rest of the API and pipelines.
• Extensible and Open Help contribute and build open adapters, and use our flexible API format to stay at the cutting edge.

Quick Start

While we're working on getting the cloud version of this product ready, you can get started with your own deployment by following the instructions below.

Prerequisites

To run the deployment, you need an AWS account with appropriate permissions, and Serverless Framework installed locally with your credentials set up.

Run:

git clone https://github.com/exemplaryai/ai-engine.git
cd ./ai-engine
yarn install

Set up providers

In serverless.yaml, set the following values under environment:

• For Deepgram - DEEPGRAM_API_KEY Get it here here
• For AssemblyAI - ASSEMBLYAI_API_KEY Get it from your AssemblyAI Console, after you've created an account, from under the Developers tab here
• For AI21 - AI21_API_KEY Get it from your account page, after you've created an account. Your AWS account you are deploying to will be used for AWS Comprehend & Transcribe jobs.

Now that you've set up your provider keys, run:

yarn run-deploy

To run it locally on your dev environment, run:

yarn start

Alternatively, get started instantly with our exemplary.ai cloud offering (Coming Soon)

Usage

curl --location --request POST 'http://localhost:4000/v1/transcript' \
--header 'Authorization: Bearer <Your-Token>' \
--header 'Content-Type: application/json' \
--data-raw '{
         "url": "https://bw8pqua-9mxfd7.s3.amazonaws.com/m/snl-zoom-call.mp4",
         "provider": "deepgram",
         "speaker_labels": true,
         "summarize": false,
         "punctuate": true,
         "language": "en-US",
         "questions": "aws.comprehend",
         "sentiment": "google.cnl",
         "entities": "aws.comprehend"
}'

This requests creates a transcription job on a wav file, using Deepgram to obtain a transcript, along with speaker labels, punctuation, and with the language set to en-US (or a supported BCP 47 language code). Questions and Entities will be extracted using AWS Comprehend, while Sentiment will be extracted using Google Cloud Natural Language. You can read more about language codes, and additional options we expose to you for transcript creation at the API Reference, here. Feel free to switch around the supported providers, and let the API abstract away the provider specific details.

Query your created transcripts and their status:

curl --location --request GET 'http://localhost:4000/v1/transcript' \
--header 'Authorization: Bearer <Your-Token>'
