What are the distinctive hurdles of voice tech compared to chat?


Reading involves actively processing information, requiring users to engage with the text to comprehend its meaning. In contrast, listening to a voice assistant can be a more passive experience, as users simply receive spoken information without the need for active participation. With chatbots, users must actively type responses, fostering engagement through interaction.

Cognitive Load

Text-based chatbot interactions leave a written record of the conversation, allowing users to refer back to previous messages for context or clarification. This written record can reduce cognitive load by providing a reference point for ongoing interactions. In contrast, voice interactions do not leave a tangible record, relying solely on auditory memory or log files. Designing for voice assistants requires careful consideration of cognitive load, as users must retain information without a written reference.


Voice interactions often require prompt responses to maintain the flow of conversation, as delays can disrupt the natural rhythm of communication. Users must respond within a short timeframe, typically a few seconds, to keep the interaction seamless. This time constraint can create a sense of urgency, placing pressure on users to formulate responses quickly.

In contrast, chatbot interactions afford users more flexibility in timing, allowing them to read, ponder, and research before responding. This difference in timing can influence the pace and tone of the interaction, shaping the user experience accordingly. Additionally, text-based interactions enable the inclusion of multimedia elements such as links and images, enhancing the richness of communication beyond voice-based interactions.

Considerations for crafting experiences tailored to voice assistants

Considerations in Voice Assistant Design:

  • Error Handling: Voice interactions require robust error handling due to potential misunderstandings caused by background noise or accents. Implicit or explicit confirmation prompts can enhance user understanding and reduce errors.
  • Limiting Options: Presenting concise lists of options is crucial in voice interfaces to reduce cognitive load. Limit choices to three options at a time and provide alternative selection methods to improve user experience.
  • Message Length: Keep voice messages short to prevent cognitive overload and maintain user engagement. Use techniques like the “one breath test” and the “Jenga technique” to trim unnecessary information and streamline communication.
  • Skip Redundancy: Avoid unnecessary repetition in voice responses. Instead of restating actions, use sonar notifications or brief confirmations to inform users of task completion or status changes.
  • Simplify Language: Use clear and concise language in voice assistant responses to enhance user comprehension and streamline interactions. Simplify scripts through iterative refinement and focus on essential instructions without unnecessary verbosity.
