nuance

nuance-nodejs

A simple Nuance HTTP Client for NodeJS.

Installation

Download the source or use NPM:

npm install nuance --save

##Usage First, you need to create a new Nuance instance:

var Nuance = require("nuance");
var nuance = new Nuance();

The next step is loading the file:

nuance.loadFile(path, function(fileLoaded){
	if(fileLoaded){
		//continue
	}
	else{
		//Could not read the file, do something here
	}
});

After the file has been loaded successfully, we may procceed with sending the request:

nuance.sendRequest(language, id, additionalHeaders, function(error, response){
	console.log(response);
});

language = The language code (for example: "eng-USA").

id = The user's identifier - you should send here a random generated string for each user.

additionalHeaders = An object containing more headers than the default headers

error = If the request failed for some reason, the error will be the response object.

response = If successfull, returns an array with whatever Nuance analyzed. If not successfull - it will be undefined.

A whole code should look like this:

var Nuance = require("nuance");

var nuance = new Nuance();

nuance.loadFile(path, function(fileLoaded){
	if(fileLoaded){
		nuance.sendRequest(language, id, additionalHeaders, function(error, response){
			if(error){
				//An error has occurred
			}
			else{
				console.log(response);
			}
		});
	}
	else{
		//The file probably doesn't exist
	}
});

##Notes

1. If you receive error 500 with AUDIO_INFO - the headers you had sent are probably wrong.
2. Please make sure you are sending the right headers with the right language.
3. Feel free to modify the default headers in the index.js file, at the moment they are set to handle AMR files.
4. You may replace the default headers by suppling additionalHeaders, so you don't have to change the default headers in the index.js file.
5. You need to supply apiKey and appID in the index.js file.
