Overview

Package voicemail detects whether an outbound call reached a person or a voicemail system. The Processor watches the LLM's classification output for a decision tag — <voicemail></voicemail> or <human></human> — and fires the matching callback, so the app can leave a message and hang up, or start the conversation. Drive it with an LLM prompted to emit one of those tags after hearing the first utterance. The decision tags are stripped from the output.

Types

type Config 

type Config struct {
	// OnVoicemailDetected is called when the classifier decides the call reached
	// voicemail. It fires after VoicemailDelay.
	OnVoicemailDetected func()
	// OnConversationDetected is called when the classifier decides a person
	// answered.
	OnConversationDetected func()
	// VoicemailDelay delays the voicemail callback — for example to let the
	// greeting finish before leaving a message; 0 fires immediately.
	VoicemailDelay time.Duration
}

Config configures a voicemail Processor.

type Processor 

type Processor struct {
	*processor.Base
	// contains filtered or unexported fields
}

Processor classifies a call as voicemail or human from the LLM's decision tag and fires the matching callback exactly once. It strips the decision tags from the forwarded text.

func New 

func New(cfg Config) *Processor

New builds a voicemail Processor.

func (*Processor) Cleanup 

func (p *Processor) Cleanup(ctx context.Context) error

Cleanup stops the pending voicemail timer and tears down the processor.

func (*Processor) ProcessFrame 

func (p *Processor) ProcessFrame(ctx context.Context, f frames.Frame, dir processor.Direction) error

ProcessFrame strips and acts on the decision tags in the LLM text stream.
