sc-voice

Javascript implemenation of SuttaCentral Voice Assistance (SC-Voice) for vision-impaired. Includes:

• TTS adapter for Amazon AWS Polly Text-to-Speech
• romanized search for Pali terms (e.g., Mulapariyayasutta vs. Mūlapariyāyasutta)
• integration with SuttaCentral bilara-data

Prerequisites

• Linux Debian 10 or Ubuntu 20.04
• Nodejs 14.x
• AWS Polly account (required)

Installation

With a Linux console, install the software:

git clone https://github.com/sc-voice/sc-voice.git
cd sc-voice

Initialization requires super user access for your computer and you will be asked to enter your computer superuser password.

./scripts/init.sh

Now update the content but do not reboot (i.e., Respond with no when asked to reboot)

./scripts/update-latest

As part of installation you will need to configure the AWS Polly TTS service adapter.

Configure Amazon AWS Polly

The Amazon AWS Polly Text-to-Speech service can be used to convert sutta text to speech. To enable AWS Polly, you will need to configure your credentials

Login to your AWS account and go to the IAM dashboard|Delete your root access keys|Manage Security Credentials|Access Keys...|Create New Access Key

aws configure

Launch localhost server

npm start

Open up localhost in your local browser and you will see Voice. When you are done with voice, type CTRL-C in the terminal.

Unit tests

npm run test

Unit tests take about 2 minutes. The unit tests require AWS Polly.

To execute a single unit/test, simply insert the text TESTTEST into the it("...") title argument. Then run npm run test:test, which selectively tests such unit tests whenever a source file changes. This makes quick work of debugging or implementing a feature.

Test failures

• Some tests validate online APIs and may fail due to timeouts or EAI_AGAIN responses. Re-run tests and they should pass.
• Some tests validate online content which may change. For example, the number of search results may change slightly. Update the unit tests accordingly and re-run tests.
