Navigation instruction changes volume halfway through the sentence when using Android Auto

Description

I’m experiencing a reproducible issue where the volume changes halfway through every spoken navigation instruction when using Waze with Android Auto.

Environment

  • Phone: Google Pixel 10
  • Android Auto: Wired
  • Vehicle: Volkswagen Polo AW
  • Waze version: June 30, 2026 release

Steps to reproduce

  1. Connect the phone to the car using wired Android Auto.
  2. Start navigation in Waze.
  3. Listen to the spoken navigation instructions.

Expected behavior
The entire navigation instruction should be played at a consistent volume.

Actual behavior
The first part of the navigation instruction is played at the expected volume, but the second part suddenly becomes much louder.

For example:

  • “In 300 meters…” → normal volume
  • “…turn left.” → significantly louder

This happens consistently and is noticeable on every navigation instruction.

Additional observations

  • Google Maps on the same phone, using the same wired Android Auto connection and the same vehicle, does not exhibit this issue. Its voice guidance remains at a consistent volume throughout each instruction.
  • This suggests the issue is specific to Waze rather than Android Auto, the phone, or the vehicle infotainment system.
  • It almost sounds as if the navigation instruction is split into two separate audio segments, with the second segment being played through a different audio output, audio focus, or gain level than the first.
  • I found reports from other users describing similar behavior where the first and second parts of a navigation instruction are played at different volume levels, suggesting this may be a broader Text-to-Speech or audio routing regression.

Does more Waze-user experience this volume issue?
Does somebody know if this issue has been acknowlegde by Waze?
If there is a solution for this issue planned?

I am experiencing the same but it gets quieter rather than louder in the second half of the sentence. Google maps is fine.
