AccentSense AI

This AI-driven solution allows Alexa to accurately recognize and respond to users’ voice commands without requiring them to adjust their speech patterns.

Problem Statement  

How might we improve Amazon Alexa’s ability to accurately understand diverse accents and dialects using AI?

Problem Background  

Amazon Alexa is widely recognized for its smart assistant capabilities, allowing users to control smart devices, play music, and retrieve information using voice commands. However, users with regional accents, ethnic dialects, or non-standard English pronunciation often face encounter difficulties in being accurately understood.  

This is especially frustrating when requesting specific song titles in African languages or dialect-heavy music genres, as Alexa frequently misinterprets the request and plays incorrect songs. Accent bias in voice assistants impacts user adoption, retention, and satisfaction.

Research Insights

Consumer Interview Questions and Responses  

User Pain Points

Using Reddit forums and WhatsApp groups, we identified key frustrations among Amazon Alexa users:  

Supporting Data

44.4% of people we surveyed feel frustrated or annoyed when Alexa does not recognize their accent  

Feedback

Our preliminary user research to validate this problem with users found that most participants felt excluded from the mainstream voice assistant experience due to a lack of regional accent recognition.  

Market Opportunity  

Enhancing Alexa’s ability to recognize diverse accents is not just a user experience improvement; it represents a big business opportunity for Amazon.  

Market Size & Reach  

  • United States: Approximately 25 million individuals in the U.S. speak a language other than English at home, representing a large customer segment for Alexa.  
  • Canada: A significant portion of the population speaks languages other than English or French, creating a need for better multilingual voice recognition.  

Customers and Business Impact  

Customer Benefits:  

  • Seamless experience: Users no longer need to modify their speech.  
  • Enhanced music request accuracy: Non-English and dialect-heavy music titles are correctly recognized.  
  • Improved daily interactions: Smart home controls, reminders, and entertainment features work without misinterpretation.  
  • Higher satisfaction and adoption: Increased engagement among users who previously avoided Alexa due to poor recognition.  

Business Benefits for Amazon

  • Higher retention rates: More users will continue using Alexa instead of switching to competitors.  
  • Increased usage time per session: Users will rely on Alexa for more tasks without frustration.  
  • Better customer insights: Improved recognition will allow Amazon to gather better data on diverse speech patterns.  
  • Revenue growth: Improved usability will lead to increased subscription and device sales.  
  • Market Expansion: Addressing this gap would help Amazon tap into new and underserved customer bases, both within North America and internationally.  

 

Landing on the Solution

Based on our target users’ pain points, we knew we wanted to work on the following features:  

  1. Accent Adaptive AI – A machine learning model that improves Alexa’s understanding of Nigerian American speech patterns over time.
  1. Personalized Pronunciation Training – Users can provide verbal corrections when Alexa misinterprets a request.
  1. Afrobeats Genre Optimization – A dedicated music model that enhances recognition of Afrobeat artist names and song titles.

📌 Prototype Feedback:
💡 Users preferred real-time feedback loops where Alexa learns from mistakes and improves gradually.

Working on AccentSense AI reinforced the importance of inclusive technology. Through user research and iterative design, I witnessed how small product adjustments can significantly improve the experience for underserved audiences.

Additionally, this project highlighted how AI can optimize efficiency and enhance accessibility.

From a skills perspective, I expanded my toolkit by learning Figma, Lucidspark, and new prioritization frameworks such as R.I.C.E and Effort vs. Reward.

These methodologies helped refine decision-making and ensure a structured approach to feature development

  1. Adapting to an Established Team: Joining the team in week 6 of 8 was challenging, as I had to quickly adapt to existing workflows, dynamics, and goals. This mirrors real-world situations where you often integrate into teams mid-project, and flexibility is essential.
  2. Work-Blocking for Efficiency: With only two weeks to complete the project, I learned the importance of a structured work-blocking system. This approach allowed me to manage my time effectively and meet deadlines under pressure.
  3. Making Data-Driven Design Decisions: Unlike my past projects, I had to rely on research conducted by others. This was a valuable experience in using pre-existing data to guide design decisions, helping me focus on the core insights without starting from scratch.

I learned how important communication is when working with a team. Communication provides understanding, advice, ideas, and much more. While working with the product team, I’ve found that communication keeps everything flowing smoothly. Working with a team also showed me that every member brings something different to the table and we all have to work together in order to align and meet our end goal.
