Conversation
Currently Discord, Slack, and Telegram all hardcode *voice.GroqTranscriber
as their transcription dependency. This makes it impossible to swap in a
different STT backend without changing each channel file.
Add a Transcriber interface to pkg/voice/transcriber.go:
type Transcriber interface {
Transcribe(ctx context.Context, audioFilePath string) (*TranscriptionResponse, error)
IsAvailable() bool
}
GroqTranscriber already implements this interface (no change to its
implementation). Update Discord, Slack, and Telegram to depend on the
interface instead of the concrete type.
No behaviour change — this is a pure refactor that enables future STT
providers (e.g. local Whisper) to be dropped in without modifying channel
code.

Summary
Currently Discord, Slack, and Telegram all hardcode
*voice.GroqTranscriberas their transcription dependency. This makes it impossible to swap in a different STT backend without modifying every channel file.This PR adds a
Transcriberinterface topkg/voice/transcriber.goand updates the three channels to depend on it instead of the concrete type.Changes
pkg/voice/transcriber.go: addTranscriberinterface (Transcribe+IsAvailable)pkg/channels/discord.go:*voice.GroqTranscriber→voice.Transcriberpkg/channels/slack.go: samepkg/channels/telegram.go: sameGroqTranscriberalready satisfies the interface — zero behaviour change.Why
This unblocks adding alternative STT providers (e.g. local Whisper — see follow-up PR) without touching channel code. It also aligns with how the
Synthesizerinterface works for TTS.Tests
All existing tests pass (
go test ./...).
