Introduction to Voice Action Design Sprint model for prototyping experiences with Google Assistant.
01:08
Design sprints at Google aim to speed up product development and decision-making.
The framework includes six phases that support divergent and convergent thinking, based on traditional UX practices.
The Voice Action Sprint model merges design sprints with role-playing workshops, featuring eight phases for inclusive role-playing and iteration.
The goal is to empower viewers to conduct their own Voice Action Sprints.
Voice Action Design Sprints for voice products focus on product direction, brand persona, and dialogue development.
04:20
Planning is key for successful sprints, starting with defining the challenge and scope.
Examples with Filtrete and H&M show different sprint scopes, from broad visioning work to specific audience focus.
Deliverables of Voice Action Design Sprints include key use cases, brand persona, and voice prototypes.
Narrowing the sprint focus to specific use cases or contexts is an option, along with lightning talks and assembling the right team for planning successful sprints.
Preparation for Sprint and User Testing.
07:56
Recruit a team with a Dialog Flow developer and five user test participants, as well as necessary equipment.
Understanding Phase Techniques.
Utilize lightning talks, affinity mapping, and experience mapping during the understanding phase for brainstorming and insights.
Conversation Design Principles.
Implement conversation design principles like the cooperative principle by Paul Grice for successful communication.
Visual vs. Conversation Design.
Understand the differences between visual and conversation design, with conversations requiring real-time capture and aiming for truth, relevance, informativeness, and clarity.
Importance of voice-forward applications and conversational tasks.
10:43
Voice commands are useful for interacting with recipe apps and other tasks when hands are occupied.
Tasks should be chosen for voice interaction based on user convenience and value.
Meditation apps are highlighted as examples of tasks suitable for voice interaction.
Voice-forward applications are practical and valuable in various scenarios.
Highlights of the video segment:
12:05
Headspace offers meditation options for beginners, emphasizing the importance of a beginner's mind in daily life.
Sephora provides skincare advice tailored to different skin types and care tips.
Filtrete offers smart filters for air purifiers that indicate when they need replacing and provide air quality information.
The importance of understanding user context for voice assistants, including data sources like call centers and user research methods, is emphasized.
Affinity mapping exercises are recommended to identify design opportunities.
Importance of creating a brand persona that matches brand identity.
15:56
Conveying the essence of the brand through the persona's voice and characteristics is crucial.
The persona reflects social status, gender, age, education level, and locale, impacting perceptions of intelligence, trustworthiness, and likability.
Creating the right persona is essential for establishing a connection with users in the first few seconds of interaction.
Emma Wiggle from the Wiggles is cited as an example of a successful persona engaging children in interactive storytelling adventures.
Creating a fashion and style maven persona for H&M.
18:12
Aligning brand persona with user value and success metrics for products is crucial.
Utilizing a user value matrix to map conversational tasks.
Using traditional design sprint methods like crazy 8's sketching to generate ideas and test assumptions.
Team presentation and assumptions exercise are valuable steps in the design process.
Importance of identifying unknowns and assumptions in design sprints.
22:32
Limited time for user testing, need for efficient prototyping.
Workshop methods from improv used in role play, iterate, and decide phases.
Creating sample dialogues with clear brand persona and natural interactions.
Team sits back to back during voice-only conversations to ensure natural flow and persona flavor.
Key highlights for successful user interactions in conversation design.
25:43
Natural and realistic conversations are crucial for user success without the need to learn new things.
Clear calls to action or questions at the end of each dialog turn are essential for guiding users.
Contextual repair mechanisms are necessary for getting back on track when errors occur.
Prototyping involves decisions on voice recording or Dialog Flow, final script preparation, and incorporating contextual repair.
Benefits of creating a Wizard of Oz prototype using voice recording for user testing.
28:10
Emphasizes aligning the prototype with the user interview script and covering all scenarios.
Process involves setting up a test environment, running a usability test, synthesizing feedback, and identifying next steps.
Goal is to create a realistic experience for users and iterate as needed.
Decoupling feedback about the platform from the actual task is crucial in assessing the task's usefulness in a voice action sprint.
Importance of team collaboration in reviewing findings and deciding on prototyping and future steps in the Filtrete sprint example.
29:52
Value of documenting learnings and creations during the sprint for stakeholder approval.
Scheduling follow-up testing and iterations based on test outcomes is suggested.
Need to establish timelines for development and create a product roadmap.
