# NousResearch/hermes-agent · TTS/STT import fallback and lazy-install robustness

## Open now

- Nothing open on GitHub.

These items address failures in TTS and STT tooling when lazy dependency installation fails or packages are available via PYTHONPATH, adding fallback logic to raw imports and improving provider robustness around device config and container handling.

## TL;DR

- 5 member(s): 0 open issue(s), 1 closed issue(s), 0 open PR(s), 1 merged PR(s), 3 PR(s) closed without merging.
- A fix was merged to main in PR #73510. Verify it addresses your case.
- **Recommended:** read PR #73510 (and any competing PRs below) before filing. Confirm the merged change covers your symptom.

## Maintainer resolution verdict

- Internal-tracker verdict over this cluster's issue members: `resolved` · deciding PR(s): `pr-73510`. This is distinct from the fix status above. Weigh it yourself.

## How this cluster was grouped

- Link evidence (`STRUCTURAL_SPANNING`): every member is connected by structural evidence: shared changed files, or a closing/superseded reference.
- Pairwise link density `0.40`: the share of member pairs that carry a link, counting a structural link in full and a relevance-only link at 0.36. `1.00` means every pair is linked.
