Build “Voice Channels” with, your virtual assistant

Share this post: and IBM—creating new forms of Human-Machine-Interaction (HMI). Our service, which is available on the IBM Bluemix platform, caters to companies who want to accelerate the pace of innovation and get to market fast with new forms of HMI for their customers and also for internal applications such as business analytics. Simply stated, our goal is to provide an eco-system where you can use your voice to accomplish practically any task for nearly any situation.

With, users just say what they want to have happen, and a partner’s Voice Channel is activated. See our IBM Cloud Marketplace solution here: – Voice Channels

Building “Voice Channels” on the interface

A Voice Channel is made up of trigger patterns (phrases), which Moni recognizes to perform a set list of actions or being a two-way dialog with the end-user. Let’s imagine the following use case:

Your company is selling cars, you are looking for new innovative ways to interact with your customers. How can help you? First things first you could create a new Voice Channel listening to the trigger pattern “I want to buy a car”. Then you create a workflow on Node-RED defining what happens whenever someone on says the trigger pattern. For example, you could advise Moni to ask the user “What type of car are you looking for?” and the customer would continue the interaction with Moni, his/her virtual assistant. Node-RED thereby allows you to query your databases or APIs for price information, availability and more. The whole process is mapped out visually on Node-RED. The interaction takes place using the apps or the website.

By owning trigger patterns, companies can create Voice Channels which will be activated every time Moni hears that phrase, or even similar phrases. Building a Voice Channel is easy for even a beginning developer. Using the Node-RED boilerplate, it’s simple to visually wire together APIs and dialogs. You as a developer don’t have to worry about servers or hardware, and you can simply focus on coding and defining the user experience. Ready to try it?

Getting started on

First you subscribe to on the IBM Marketplace. You can start with the free developers edition to create your Voice Channels without publishing them. Starting the subscription process, you will be asked for a user. You can signup for free if you don’t have a user already.

After the service is connected, you will need to deploy the Node-RED environment on IBM Bluemix that allows you to define the interaction process. Note that does not have access to your Node-RED environment – you don’t need to share your data. Technically Moni will just “ask” your Node-RED environment for information and will only have access to the output you send Moni via the nodes. You can use the Deploy-To-Bluemix button to initialize your Node-RED environment on Bluemix:

On your newly deployed Node-RED environment, create your Voice Channel using the nodes. The demonstration below walks through the same steps:

You are now ready to test your Voice Channel!

I followed all the steps per the video guide, but upon giving the trigger pattern in, am always seeing ‘Sorry something went wrong’ message.
Is it required to add pattern on the developers page? If yes, what should be given on the target URL?

Monitoring & logging for IBM Bluemix Container Service with Sematext

In this blog post we discuss how Sematext integrates with IBM Bluemix Container Service to provide monitoring and logging visibility of your containerized applications, as they run in production. In the sections below, we demonstrate how to set up a Kubernetes cluster in Bluemix and how to set up Sematext in this cluster. IBM Cloud has monitoring and logging capabilities in the platform, but we know our customers operate in a multi-cloud or hybrid cloud environment and we are very excited to partner with Sematext, enabling operational consistency across those environments. We worked with Alen Komljen, an Automation Engineer from Sematext, to create the following content and perform the technology validation.
