List Voices
List available TTS voices across every provider, filterable by model `brand`.
A unified, normalised catalog spanning ElevenLabs, Together, and DeepInfra:
- **Together** voices are fetched live from its `/v1/voices` endpoint
(Cartesia and any other dynamic models).
- **Kokoro / Orpheus** preset voices (shared by Together + DeepInfra) come
from a static catalog — DeepInfra exposes no per-model preset listing.
- **ElevenLabs** account voices are fetched live.
Filters (case-insensitive): `brand` (e.g. `elevenlabs`, `hexgrad`,
`canopylabs`, `cartesia`), `model` (canonical model_id), and `search`
(substring match on voice id / name). Per-provider fetches are best-effort —
a provider that errors is skipped rather than failing the whole listing.
