\n\n\n## Description\nThis package allows real-time speech-to-text (S2T) functionality using a WebSocket which streams audio data to AWS Transcribe. Two reasons why the team at [Buccaneer](https://www.buccaneer.ai) decided to write a package for it:\n\n1. At the time this was written in Fall 2019, the [Transcribe API](https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/TranscribeService.html) in `aws-sdk` did not support real-time audio streaming and Amazon did not provide an official JavaScript client for real-time subscription. For many speech-to-text use cases, real-time transcription is mandatory. (**Tip**: If your goal is to transcribe an audio file in its entirety and you can wait for the entire file to be processed, then you can use the `aws-sdk` and you don't need this library!)\n\n2. This implementation makes it easy to plug AWS Transcribe into [RxJS 6](https://rxjs-dev.firebaseapp.com/api) pipelines.\n\n3. This package encapsulates the business logic of AWS Transcribe streaming into a separate `npm` package so that applications can focus on what they're good at and don't need to worry about the internals of how AWS Transcribe processes audio data streams.\n\n## Installation\n```bash\nyarn add @bottlenose/rxtranscribe\n```\n\n```bash\nnpm i --save @bottlenose/rxtranscribe\n```\n\n## Compatibility\n\n|Platform|Support|\n|--------------|:-----------:|\n|node.js (>10.8)|ā
|\n|Browsers|ā|\n|React Native|ā|\n|Electron|ā|\n\nš” This package has only been tested in the node.js environment. If it doesn't work isomorphically, it could probably be modified to do so without much effort. The authors haven't one so because running it on client devices does not seem like an advisable design for production situations. But if you want to take a stab at implementing isomorphic support, [contact us](mailto:opensource@buccaneer.ai)!\n\n## Basic Usage\n```javascript\nimport { transcribe } from '@bottlenose/rxtranscribe';\n\n// The pipeline takes a stream of .wav audio chunks (Buffer, String, Blob or Typed Array)\nconst buffer$ = chunk$.pipe(\n map(chunkStr => Buffer.from(chunkString, 'base64')),\n transcribe({})\n);\n```\n\nš” One limitation of the current package is that it currently only supports `.wav` files as inputs, which are [encoded as](https://cloud.google.com/speech-to-text/docs/encoding) .mp4 files. It would be nice to support a wider variety of file types. If you know how to do this and want to help implement this functionality, please [contact us](opensource@buccaneer.ai).\n\n## Documentation & Guides\n- [Documentation](https://buccaneerai.gitbook.io/bottlenose/data-analysis/rxtranscribe)\n- [Full list of operators](https://buccaneerai.gitbook.io/bottlenose/data-analysis/rxtranscribe/operators)\n- [Guides](https://buccaneerai.gitbook.io/bottlenose/data-analysis/rxtranscribe/guides)","readmeFilename":"README.md","_id":"@bottlenose/rxtranscribe@0.6.0","_nodeVersion":"12.13.0","_npmVersion":"lerna/3.20.2/node@v12.13.0+x64 (darwin)","dist":{"integrity":"sha512-dxZWMcZCGgW/m3qB5wGw/gIW3qPVIHk+4TJbV74qmjfm2ZkFfkce1vGI6+wzT9/LfCNwYtS/qbaNYeV74Oa40g==","shasum":"459f4608ddb3f3b380da53a9dbedae3c61b027f0","tarball":"https://registry.npmjs.org/@bottlenose/rxtranscribe/-/rxtranscribe-0.6.0.tgz","fileCount":16,"unpackedSize":20768,"npm-signature":"-----BEGIN PGP SIGNATURE-----\r\nVersion: OpenPGP.js v3.0.4\r\nComment: https://openpgpjs.org\r\n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\n+SF8\r\n=DwzP\r\n-----END PGP SIGNATURE-----\r\n","signatures":[{"keyid":"SHA256:jl3bwswu80PjjokCgh0o2w5c2U4LhQAE57gj9cz1kzA","sig":"MEYCIQDj1F2CJ+vb89JeW1zH4VUA+LBtkxRLSjH2XfggEmPRpAIhAOnkPTyyYufozsBejmiQoFJuo0xt4cXK9JGCdoofa6SG"}]},"maintainers":[{"name":"brianbuccaneer","email":"brian@buccaneer.ai"}],"_npmUser":{"name":"brianbuccaneer","email":"brian@buccaneer.ai"},"directories":{},"_npmOperationalInternal":{"host":"s3://npm-registry-packages","tmp":"tmp/rxtranscribe_0.6.0_1586196818322_0.365418394140133"},"_hasShrinkwrap":false},"0.1.1-beta.19":{"name":"@bottlenose/rxtranscribe","version":"0.1.1-beta.19","description":"š Realtime speech-to-text (S2T) transcription with RxJS","main":"build/index.js","repository":{"type":"git","url":"https://github.com/buccaneerai/bottlenose/tree/master/packages/rxtranscribe"},"publishConfig":{"access":"public"},"author":{"name":"Buccaneer LLC","email":"opensource@buccaneer.ai"},"license":"MIT","private":false,"bugs":{"url":"https://github.com/buccaneerai/bottlenose/issues"},"keywords":["speech-to-text","s2t","transcription","transcribe","voice control","speech recognition","AWS","AWS Transcribe","rxjs","reactive","observables","stream","streaming","realtime"],"dependencies":{"@aws-sdk/eventstream-marshaller":"^0.1.0-preview.2","@aws-sdk/util-utf8-node":"^0.1.0-preview.1","@bottlenose/rxws":"^0.1.1-beta.19+071a6b4","deepspeech":"^0.6.1","lodash":"^4.17.15","qs":"^6.9.1","rxjs":"^6.5.4"},"devDependencies":{"@bottlenose/rxfs":"^0.1.1-beta.19+071a6b4","optimist":"^0.6.1","prompt":"^1.0.0"},"browserslist":[],"scripts":{"build":"BABEL_ENV=build babel src --out-dir build --source-maps --extensions .js --config-file ../../babel.config.js --delete-dir-on-start --no-comments","lint":"eslint -c ../../.eslintrc ./src","test":"mocha --exit ./src/**/*.test.js ./src/*.test.js","test:watch":"yarn test -- --watch","prepublishOnly":"yarn lint && yarn test && yarn build","demo:run":"yarn build && BABEL_ENV=build yarn babel-node --config-file ../../babel.config.js ./demo/runDemo.js"},"gitHead":"071a6b4e557dd18ed7591ad2da5ba4cb7316e9a6","readme":"[](https://circleci.com/gh/buccaneerai/bottlenose/tree/master)\n[](https://opensource.org/licenses/MIT)\n\n \n\n\n## Description\nThis package allows real-time speech-to-text (STT) functionality to be performed on audio streams.
