This app was an initial prototype to test the quality of IBM STT, and is no longer activly supported I am now working on a more full fledge version at https://github.com/OpenNewsLabs/autoEdit_2 ( http://www.autoedit.io ).
To use this app you need to get IBM Watson API keys for their speech to text service, by making an account with Bluemix
If you clone the repo you can start the app with npm start.
Or you can get the latest release packaged and ready for use here
This is a Tray Menu app.
First you Select Media, audio or video you'd like to transcribe.
Notifications show when a transcription as started and when it's finished.
On completion a editable text area shows you the transcription.
By default the transcription is also saved to clipboard.
You can disable Autosave to clipboard if working on text editing or making use of the system clipboard for some other program to avoid it overwriting something else you might be doing with it.
First time you start the application you'd be prompt to set the API keys.
Should you need to change those you can use shortcut cmd + shift + a.
These are saved inside the app as a json file wttskeys.json at the root of the application.
Which is in the .gitignore so that it doesn't accidentally gets added to git by mistake, when in development mode.
The video_to_audio module converts video or audio into IBM audio specs. Initially modified from Sam Lavine's gist.
Audio files are saved in ./tmp/audio folder.
The stt folder contains the module to interact with the IBM Speech to text API.
If you want to dive more into this their documentation on how to interact with the API is pretty good.
transcribe.js requires both modules described above and brings it all together.
Converts audio into video, and then sends it to Watson for transcriptions. Transcriptions are saved onto a text file in ./tmp/text folder.
module returns the path to the text file.
index.js abstracts transcribe.js in case the interface needs to change at a later stage.
indext.html contains the Implementation of the NWJS app.
Adding Menu Tray to the application.
See comments in the code `./index.html and nwjs wiki as well as nwjs documentation for more on this.
When a user selects a video it's transcribed, appropriate system notifications for start and end are triggered.
When done unless option is un-ticked transcription is saved to clipboard.
in which case user can click on Copy transcriptions to cliboard to get the transcriptions.
Use deploy script
deploy.js
This creates a build folder inside the repo. The build folder is also in .gitignore to avoid accidentally pushing it to remote.
To rebuild the app in NWJS refer to the documentation
Install nw-builder
install -g nw-builder
From one level above the application folder (cd .. from root of repo)
ild -p osx64 ./transcriber
creates a build folder that contains the app
