Types ¶
type LLMService ¶
type LLMService struct {
// contains filtered or unexported fields
}
LLMService implements services.LLMService using AWS Bedrock Converse API (streaming).
func NewLLM ¶
func NewLLM(cfg aws.Config, modelID string) *LLMService
NewLLM creates an AWS Bedrock LLM service from an existing AWS config.
func NewLLMWithRegion ¶
func NewLLMWithRegion(ctx context.Context, region, modelID string) (*LLMService, error)
NewLLMWithRegion creates an AWS Bedrock LLM service by loading default config (env/profile) for the given region.
func (*LLMService) Chat ¶
func (s *LLMService) Chat(ctx context.Context, messages []map[string]any, onToken func(*frames.LLMTextFrame)) error
Chat runs a completion via Bedrock ConverseStream and calls onToken for each content delta.
type STTService ¶
type STTService struct {
// contains filtered or unexported fields
}
STTService implements services.STTService using Amazon Transcribe streaming.
func NewSTT ¶
func NewSTT(cfg aws.Config, languageCode types.LanguageCode) *STTService
NewSTT creates an AWS Transcribe STT service from an existing AWS config.
func NewSTTWithRegion ¶
func NewSTTWithRegion(ctx context.Context, region, languageCode string) (*STTService, error)
NewSTTWithRegion creates a Transcribe STT service by loading default config for the given region. languageCode can be empty for default (en-US), or an AWS Transcribe language code (e.g. "en-US", "es-ES").
func (*STTService) Transcribe ¶
func (s *STTService) Transcribe(ctx context.Context, audio []byte, sampleRate, numChannels int) ([]*frames.TranscriptionFrame, error)
Transcribe sends audio to AWS Transcribe streaming and returns the final transcript as TranscriptionFrame(s). Audio must be 16-bit PCM mono at 8000 or 16000 Hz; other sample rates are not supported by Transcribe streaming.
type TTSService ¶
type TTSService struct {
// contains filtered or unexported fields
}

NewTTSWithRegion creates a Polly TTS service by loading default config for the given region. engine can be empty for default (neural), or "standard", "neural", "long-form", "generative".
func (*TTSService) Speak ¶
func (s *TTSService) Speak(ctx context.Context, text string, sampleRate int) ([]*frames.TTSAudioRawFrame, error)
Speak synthesizes text to speech and returns TTSAudioRawFrame(s). Polly PCM is 16-bit 16kHz mono.
func (*TTSService) SpeakStream ¶
func (s *TTSService) SpeakStream(ctx context.Context, text string, sampleRate int, outCh chan<- frames.Frame)
SpeakStream runs TTS and sends the resulting TTSAudioRawFrame(s) to outCh.
