CASE STUDY

Enhancing Audio Accessibility with Text-to-Speech (TTS) in Third Bridge iOS App

Overview

Third Bridge is a leading global research firm that provides investors and business leaders with critical insights through expert interviews. Their iOS app offers a vast library of interview content designed to help users gain valuable insights efficiently.

Challenge

With a growing repository of interviews — many of which are lengthy — the client faced the challenge of improving content accessibility and enhancing the listening experience for their users. Users wanted greater flexibility to consume content, especially during commutes, workouts, or multitasking scenarios.

Solution

To address this, we integrated a robust Text-to-Speech (TTS) feature into the Third Bridge iOS app. This feature allows users to listen to interviews with customizable playback options, ensuring a smooth and personalized experience.

Key Features of the TTS Integration

  • 1. Customizable Playback Controls
  • Users can adjust playback speed to suit their listening preferences.
  • Pitch control allows users to modify the tone of the TTS voice for improved clarity and comfort.
  • 2. Voice Selection
  • Multiple voice options were integrated to cater to diverse preferences and enhance engagement.
  • 3. Seamless Switching
  • Users can switch between audio files (if available) and TTS playback without disruptions. This ensures a continuous listening experience while respecting user preferences.
  • 4. Automatic Resumption
  • If a user pauses their listening session, playback resumes from the exact point they left off — whether in TTS mode or audio playback.

Results

  • Improved content accessibility, particularly for users who prefer auditory learning.
  • Enhanced user engagement by enabling content consumption during hands-free activities.
  • Positive user feedback highlighting the flexibility and improved experience the TTS feature provides.

Conclusion

By implementing TTS functionality in the Third Bridge iOS app, we successfully elevated the app’s accessibility and usability. This feature empowers users to stay informed and connected with key insights effortlessly. Our collaboration with Third Bridge exemplifies our commitment to delivering impactful solutions that improve user experience through innovative technology.
