Why Voice Matters

Voice AI turns written transport information  into clear, natural‑sounding speech that passengers can understand quickly, even in busy or noisy environments. It supports consistent communication across rail, urban transport, airports, and automotive systems.

With Acapela’s  Transport Voice AI solutions, operators can deliver reliable, real-time announcements that improve accessibility, reduce confusion, and support smoother journeys every day.

The pronunciation is perfectly tuned for local station names, even complex ones, thanks to the Lexicon Editor. Passengers feel reassured because updates are frequent, consistent, and easy to understand.

KEY USE CASES

Rail & Urban Transport

Keep passengers informed and reassured with natural-sounding, real-time voice announcements.

Acapela’s TTS voices are optimized for train stations, bus stops, metro, and tram systems, with easy pronunciation tuning via our lexicon editor. This ensures accurate, multilingual communication that improves the passenger experience at every stop.

Example: Disruption recovery at a busy metro station
  • Hear a voice sample (Taylor)

    Hear a voice sample (Taylor)

    A major metro hub experiences an unexpected delay during rush hour. Instead of generic or confusing announcements, the system uses Acapela’s TTS to deliver clear, natural, multilingual updates in real-time.

Automotive

In connected and autonomous vehicles, voice is key to a safer, more intuitive driving experience. Acapela’s digital voices support hands-free navigation, infotainment, and real-time updates.

The driver keeps their eyes on the road and hands on the wheel while receiving natural, human-like guidance. The personalized voice increases comfort and trust, while real-time updates improve safety and efficiency.

Example: Personalized Voice Assistant in a Connected Car
  • Hear a voice sample (Darius)

    Hear a voice sample (Darius)

    A driver is navigating through heavy traffic using a connected vehicle system. Instead of a generic voice, the system uses a custom or even cloned voice that sounds familiar to the driver.

Voice Branding – Create a voice passengers recognize and trust.

A custom voice helps transport brands create a consistent and recognizable passenger experience across announcements, onboard systems, apps, and kiosks.  It also gives you a greater control over pronunciation, terminology and naming conventions, helping ensure clarity across locations, destinations, and service information.
