5. How to add personality to your chatbot using custom intents and responses

Personality is the ability to express a unique and consistent character for your chatbot, such as being friendly, humorous, or sarcastic. Personality can make your chatbot more engaging, human-like, and fun to talk to. It can also help your chatbot convey your brand identity and values, and create a loyal and emotional connection with your users.

Dialogflow allows you to add personality to your chatbot using custom intents and responses. Custom intents and responses are the ones that you define yourself, as opposed to the predefined ones that come with the Small Talk feature. Custom intents and responses allow you to define your chatbot’s character and tone, and to handle specific queries that are related to your use case or domain.

To add personality to your chatbot using custom intents and responses, you need to follow these steps:

1. Go to the Intents tab: You can access the Intents tab by clicking on the Intents button on the left sidebar. You will see a list of intents that your chatbot can handle, such as Default Welcome Intent, Default Fallback Intent, and the ones that you created yourself.

An intent represents a user’s intention or goal, such as telling a joke, asking for help, or booking a flight.
3. Add training phrases: You can add training phrases by typing or pasting them in the Training Phrases section. Training phrases are examples of what users might say to your chatbot, such as Tell me a joke, Do you know any jokes?, or I need a laugh. You can add as many training phrases as you want, but try to cover different ways of expressing the same intent. Training phrases help your chatbot understand the user’s input and match it to the correct intent.
4. Add responses: You can add responses by typing or pasting them in the Responses section. Responses are what your chatbot says back to the user, such as What do you call a fish that wears a bowtie? Sofishticated., How do you make a tissue dance? You put a little boogie in it., or I’m sorry, I don’t know any jokes. Maybe you can teach me one.. You can add as many responses as you want, but try to make them varied, relevant, and consistent with your chatbot’s personality and tone. Responses help your chatbot provide a satisfying and engaging user experience.

That’s it, you have added personality to your chatbot using custom intents and responses! You can now test and interact with your chatbot using the web interface and see how it handles specific queries that are related to your use case or domain. You can also create more custom intents and responses to cover different topics and scenarios that you want your chatbot to handle.

6. How to test and improve your chatbot’s engagement and human-likeness

Engagement and human-likeness are two important aspects of chatbot quality that measure how well your chatbot can attract, retain, and satisfy your users. Engagement refers to how much your chatbot can keep your users interested and involved in the conversation.

To test and improve your chatbot’s engagement and human-likeness, you need to follow these steps:

1. Define your metrics and goals: You need to decide what metrics and goals you want to use to measure and improve your chatbot’s engagement and human-likeness. Some common metrics are conversation length, conversation depth, user satisfaction, user retention, and user feedback. Some common goals are to increase the number of turns, topics, or questions per conversation, to reduce the number of errors, fallbacks, or silences, to improve the user ratings, reviews, or referrals, and to reduce the user churn, abandonment, or complaints.
2. Collect and analyze data: You need to collect and analyze data from your chatbot’s interactions with your users, using the web interface, the History tab, and the Analytics tab on the left sidebar. You can also use external tools, such as Google Analytics, Chatbase, or Dashbot, to track and visualize your chatbot’s performance. You need to compare your data with your metrics and goals, and identify the strengths and weaknesses of your chatbot.
3. Implement and evaluate improvements: You need to implement and evaluate improvements for your chatbot, based on your data analysis and feedback. You can use the Intents tab, the Entities tab, and the Fulfillment tab on the left sidebar to modify and enhance your chatbot’s logic, behavior, and capabilities. You can also use the Small Talk tab and the Knowledge tab to enable and customize your chatbot’s small talk and personality features.
