To whom it may concern,
When I’m learning the TTS with Piper and OpenAI with my Fusion HAT, I meet an error says “ImportError: cannot import name’espeakbridge’ from ‘Piper’. I tried to re-installed the fusion-hat module, and I’m sure that I installed the right system (the bookworm one). What’s more, it can run Espeak and Pico2wave and Vosk perfectly, so I really have no idea about this problem. I’m actually a beginnner of this. Anyone help 
We have not been able to reproduce the issue you encountered.
Could you please try following the steps below to see if it resolves the problem?
Fix Steps (All steps are required)
Uninstall the conflicting piper packages (This is critical)
python3 -m pip uninstall -y piper piper-tts
sudo python3 -m pip uninstall -y piper piper-tts
You must run the commands both as a regular user AND with sudo.
This is because the customer likely ran their script using sudo python3 xxx.py.
Confirm that the Python piper package is completely removed from the system.
python3 - <<‘PY’
import importlib.util
print(importlib.util.find_spec(“piper”))
PY
The expected correct result is:
None
If a file path is printed instead → It means the package is not fully removed 
.
Reinstall / Update fusion-hat to ensure consistency.
python3 -m pip install -U fusion-hat
sudo python3 -m pip install -U fusion-hat
Run your original code again (No changes needed).
from fusion_hat.tts import Piper
tts = Piper()
tts.set_model(“en_US-amy-low”)
tts.say(“Hello! I’m Piper TTS.”)
For Maintainers: “The One-Line Diagnostic Rule”
In the future, when encountering similar customer reports, you can make a direct judgment based on this:
If the traceback contains:
from piper import espeakbridge
ImportError
Then it is 100% because the customer installed the PyPI piper or piper-tts package.
The issue is not related to hardware, the system, or the example code.
