Episode 97 - Jovo Community Plugin Tools (Part 2)
As we do #VoiceFirst development for platforms such as Amazon Alexa and Actions on the Google Assistant, we often find patterns in how we should interact with users between sessions, and the information we need to store to keep track of these interactions. Mark continues demonstrating to Allen the next two tools in the library: a streak counter and a recharge counter. References:

Episode 96 - Jovo Community Plugin Tools (Part 1)
As we do #VoiceFirst development for platforms such as Amazon Alexa and Actions on the Google Assistant, we often find patterns in how we should interact with users between sessions, and the information we need to store to keep track of these interactions. Mark shares with Allen a library he has begun for Jovo 4 to assist with some of these patterns and goes into detail about the first of these - a way to manage a randomized list of items so our visitors get a new item each time.

May 12, 2022
Episode 93 - Configure Conversations? Multivocal!
Allen has been talking about multivocal for years, but what is it, and what does it do for developers?

May 05, 2022
Episode 92 - AWS Lambda and Google Cloud Functions
Recently, AWS announced that their Lambda functions could now be invoked directly via HTTP, rather than having to go through another AWS service to access it.

April 28, 2022
Episode 91 - Bringing the Voice CMS to Sanity
In the last episode, Mark demonstrated some of his work on Jovo that would lead towards a #VoiceFirst CMS integration, and Allen commented "now all you need is a UI to manage the content". This week - Mark delivers by exploring how to use, a "headless CMS" to build the UI that will feed into the configuration.
April 21, 2022
Episode 90 - How Jovo Works (With a CMS)
Ever have one of those weekends where you have a programming idea, and you just can't get it out of your head, so you decide to code it? We all have! Mark had some ideas for how to create a Content Management System (CMS) built on top of Jovo, and he had to call Allen to share the idea and some early experiments with it. Along the way, we discuss some of Jovo's core concepts and set the stage for a #VoiceFirst CMS.

April 07, 2022
Episode 88 - OAuth Weirdness, Wisdom, and Woes
An important feature in Account Linking with both Amazon Alexa and the Google Assistant is how they both integrate with existing authorization systems using the OAuth2 protocol. But OAuth2 can be tricky sometimes, as Mark and Allen relate with some tales of woe as they've tried to integrate OAuth into their #VoiceFirst skills and actions. Definitely some weird stuff happening!
March 31, 2022
Episode 87 - Voice Content Management Systems (Part 3)
With another week to ponder the implications (and implementation), Mark and Allen are both pretty excited to discuss some thoughts around what a #VoiceFirst CMS might look like and how it would work with the Actions for Google Assistant and Amazon Alexa. Specifically, we dig a little bit into what Multivocal and Jovo are currently doing to make things easier on developers and content creators and what more needs to be done.
March 24, 2022
Episode 86 - Voice Content Management Systems (Part 2)

Some products discussed: Graph CMS Leximic multivocal Jovo
March 17, 2022
Episode 85 - Voice Content Management Systems (Part 1)
When it comes to #VoiceFirst applications, we often say that "content is king". But creating great conversations are also part of the content, and require close collaboration between the content author, the conversation designer, and the developer. Frequently updating the content can make for a better Alexa skill or Google Assistant action, but could be complicated. Mark and Allen discuss how (and why) to make this easier using a voice-oriented Content Management System (CMS). Some products discussed: Graph CMS Leximic multivocal Jovo
March 17, 2022
Episode 84 - Building a Chat App With Voice?!?!

March 03, 2022
Episode 83 - Invocations Start It Up
Let's get this #VoiceFirst app going! Mark and Allen chat about some of the complexities when it comes to starting your Google Assistant Action or Alexa Skill - either as the start of a conversation, through a "deep link" invocation, or as a "one shot" question or command. While it seems like it should be straightforward, things aren't as easy as they seem! What tricks and tools do we have at our command?
February 24, 2022
Episode 82 - What Is Modality?
Frequent listener JT asked us to explain what "modality" means. Good question, JT!

February 17, 2022
Episode 81 - HTTP For You And Me
Mark and Allen take a look at one of the foundational technologies for Alexa Skills and Google App Actions (and all of the modern web) - HTTP.

February 10, 2022
Episode 80 - An Introduction to App Actions
Mark is joined by guest host Eliza Camber, an Android developer and Google Developer Expert for the Google Assistant, to discuss what App Actions for the Google Assistant on Android are, how they bring the power of #VoiceFirst features to new and existing Android apps, how they compare to Alexa's mobile features, and how mobile devices can help future assistants with the thorny question about context.
February 03, 2022
Episode 79 - Voice At The Drive-Through
Voice AI technology is popping up in all sorts of different places, but one place that has gotten lots of news recently has been seeing #VoiceFirst processing at fast food drive-throughs.

A surprising amount of major #VoiceFirst development requires accessing other resource files your Alexa skill or Google Assistant action may need. From audio files to your privacy policy, there are all sorts of files that need to be available, and it can sometimes be confusing when they're not. Allen and Mark discuss some of the most likely scenarios and where to start looking for solutions.

While your first experiments with #VoiceFirst development may be a solo project, bigger and more elaborate projects will be done as part of a team. While we've often talked about the role of conversation designers as part of that team - what are the other team members? Allen and Mark share our experiences being part of different teams, both in how they work and how large they are, and what roles, from PM to Help Desk (and payroll!), are needed to make high quality and long lasting Amazon Alexa skills or Google Assistant actions.

Episode 69 - An Intent by Any Other Name
The concept of an Intent in the #VoiceFirst world seems straightforward - it is what a user is trying to express. But how Amazon Alexa has implemented the concept is slightly different than how the Google Assistant and Dialogflow have. Allen and Mark explore some of these differences as Allen works to prepare multivocal, a development library, for use with Alexa. Find out more:

Episode 59 - Count to Five
Inspired by a design presented at VoiceLunch US/Canada, Mark and Allen discuss how we would implement the design - consisting of keeping a "score" about user's to our skill or action, adjusting the score sometimes, and presenting different prompts based on this score. While the design seems straightforward, there are a number of interesting approaches  to the implementation.   How would you implement this design?   What libraries do you want to see to help make your implementations easier?

Episode 37 - Count on It!
Keeping count of things, how often a user has asked for help or visited your skill/action, can be a useful tool conversation designers want. But how can you code that?

Episode 33 - Presenting: APL!
Allen has some questions about the Alexa Presentation Language (APL), so who better to ask than one of the contributors to, Stuart Pockington, who joins as the guest host this week. We go through a lot of details about APL, some of which blows Allen's mind. Stuart adds this clarifying note: "For one question Allen asked about importing the APL document, I answered in a way that implies that I drop the json directly into the directive. That’s not what I do and I’d not recommend others to do it. Instead I save the APL JSON file in my project and reference that in APL directive. That gets deployed along with all my other backend code in lambda."
March 11, 2021
Episode 32 - Intents? Events? Don't be tense!
What kind of built-in Intents do Alexa and the Google Assistant provide to developers directly? How do they differ from each other, and what kind of problems do they cause?

March 04, 2021
Episode 31 - Speedy Service with a Smile
Five to seven seconds. That's how long you have for your Alexa Skill or Google Assistant Action to reply to a request from the user.

February 11, 2021
Episode 28 - Bug Busters!
Debugging is the bane of most developers, but it can be particularly tricky when it comes to voice - between the remote nature of it and the rapid response time required, it can be difficult to capture what is going wrong.
