Marsview Realtime Speech Analytics API Client end code for Marsview Speech Analytics APIs

Step 1:

Installing the dependencies for the node.js application $ npm install

Step 2:

Signup on Marsview portal and fetch API Key and API Token Update these values in app.js

Step 3:

Use the API key and secret to generate an AUTHTOKEN

Request

curl --location --request POST 'https://api.marsview.ai/cb/v1/auth/create_access_token' \
--header 'Content-Type: application/json' \
--data-raw '{
    "apiKey":    "Insert API Key",
    "apiSecret": "Insert API Secret",
	  "userId":    "demo@marsview.ai"
}'

Response

{
    "status": true,
    "data": {
        "accessToken": "DummyAccessToken",
        "expiresIn": 3600,
        "tokenType": "Bearer"
    }
}

Step 4:

Use the AUTHTOKEN to Initiate a transaction

# config data for intents and statement tag models had to be created and the ids are given here, for which apis are available

Model Configs : 

let model_configs = {
    "intent_analysis":{
        "intents":[
                    //  "intent-1c6q62hzkxj2farq-1640270029382",
                    //  "intent-1c6q62hzkxj4gm3m-1640273449953"
                    ]},
    "custom_statement_tag_analysis":{
        "statement_tag_ids":[
            //  "statement-bxllq5imjkx68e6tb-1639493995007",
            //  "statement-bxllq1zsuzkvuj44go-1636609624728",
            ],
        "use_tag_level_threshold":True
        },
    }

Request

curl -X POST https://streams.marsview.ai/rb/v1/streams/setup_realtime_stream \
-H 'authorization: Bearer <ATUHTOKEN>' \
-H 'cache-control: no-cache' \
-H 'content-type: application/json' \
-H 'postman-token: 7ba9b4b9-710a-2aca-a17e-684a0172e0e8' \
-d '{	"channels":"1","modelConfigs":model_configs}'

Response

{
    "status": true,
    "data": {
        "userId": "demouser@marsview.ai",
        "txnId": "txn-6sm91fi3vku2m3fh8-1632744795931",
        "channels": [
            {
                "channelId": "channel-6sm91fi3vku2m3fh9-1632744795931"
            }
        ]
    }
}

Step 5:

Once we have the AUTHTOKEN, CHANNEL_ID and TXN_ID, we can now initiate a new stream.

Stage 1: Copy the AUTHTOKEN, CHANNEL_ID and TXN_ID into the javascript file app.js

Stage 2: Start the app $ npm start

Stage 3: Navigate to http://localhost:1337 on your web browser (Prefer Chrome)

Stage 4: Click on start recording button

Once you click record you can start speaking into the mic and Marsview will stream back the realtime analytics of your audio and display it in the appropriate boxes

**note: Audio should be of format LINEAR16 at 16000hz for best performance
