- 39. Think outside the box
- 40. ✘ ✔ Think outside the box … literally
- 41. Best Practices
- 43. • Invocation Name • Greeting / Exit • Error Handling • Repeating • The open mic issue Best Practices - Must Do
- 44. Invocation Name OK Google, talk to … OK Google, speak to … OK Google, ask … to … Explicit triggers OK Google, order a … Implicit triggers
- 45. Invocation Name - Explicit triggers Invocation name At least two words
- 46. Invocation Name - Implicit triggers Choose intents
- 47. Greetings - Don’t be a bore! Hello, and welcome to … Hello! This is … ! Glad to see you. Welcome to … These will be cycled
- 48. Greetings - Return Visitors Hello, and welcome to Do It Already. I can tell you about your due tasks or add a new task to the list. What would you like to do? Welcome back to Do It Already! You’ve got three due tasks today. Here is the first one: “Deliver a kick-ass talk at MobileTechCon.” Now get cracking!
- 49. Greetings - Return Visitors function welcome(app: DialogflowApp) { if (app.getLastSeen()) { app.ask("Welcome back to Do It Already!") } else { app.ask(strings.welcome()) } }
- 50. Exit / Farewell Goodbye! Goodbye, come back soon! actions_intent_CANCEL
- 51. Error Handling What’s the priority for this task? … ⚡ No input What’s the priority for this task? Gobbledygook ⚡ No match
- 52. Error Handling What’s the priority for this task? … What’s the priority for this task? Gobbledygook • Always be helpful • Try to get the conversation back on track • Be progressively more helpful and provide more detail / hints • Give up after 3 attempts
- 53. Error Handling - Strategies Rapid reprompt • “What was that?” • “Say that again?” Reframe the question • “What time is this for” —> “Sorry, what time?” • “For when?” —> “What time would you like to book this for? Ask another way • “If it helps, we can do this one piece at a time.” Be ready for questions about the question • “I have your name and email from your account, so now all I need is your phone number.” Be proactive • I could put you down for 6 for now, does that work? • Do you want to finish this later?
- 54. Replay information at the user’s request It seems like the flight to San Francisco is the 7:05am flight via London Heathrow. Would you like to book it now? Sorry, can you say that again?
- 55. Replay information It seems like the flight to San Francisco is the 7:05am flight via London Heathrow. Would you like to book it now? Sorry, can you say that again? • Keep track of the last messages the app sent • Implement a repeat intent • Prefix the last message with a randomised repeat string
- 56. Replay information const REPEAT_PREFIX: [ “Sorry, I said “, “Let me repeat that.” ]; function repeat (app) { let repeatPrefix = promptFetch.getRepeatPrefix(); app.ask(repeatPrefix + app.data.lastPrompt, app.data.lastNoInputPrompts); }
- 57. The open microphone issue
- 58. The open microphone issue function areWeThereYet(app) { const response = “We will arrive very soon. Promised.” app.ask(response); } function quit(app) { const response = “It has been nice talking with you.” app.tell(response); } Microphone closed Microphone open No prompt 😱
- 59. The open microphone issue app.ask(); app.tell(); The conversation will go on, and your message needs to end with a prompt The conversation will end after this turn. Don’t include a prompt.
