Release notes

Sourced from pipecat-ai[gladia,runner,silero,webrtc]'s releases.

v1.5.0

Added

• Added TogetherSTTService and TogetherTTSService for real-time speech-to-text and text-to-speech using Together AI's WebSocket APIs. (PR #4054)

• Added per-sentence synthesis mode and zero-shot audio prompt support to NvidiaTTSService, letting NVIDIA TTS users choose between stitched and per-request synthesis flows and configure voice-cloning prompts for supported models. (PR #4742)

• Added on_heartbeat_timeout event handler to PipelineWorker, fired when a heartbeat frame is not received within the monitor timeout period. (PR #4761)

• Added Time To First Audio (TTFA) metrics to TTS services, reported as TTFAMetricsData alongside the existing TTFB metric. TTFA measures the time to the first audible sample — TTFB plus the leading silence many providers pad onto the start of a response — so comparing the two shows how much perceived latency is padding versus service response time. Audible onset is detected from short-time RMS energy (detect_speech_onset in pipecat.audio.utils), which rejects noise-floor blips and brief transients; the MetricsLogObserver surfaces the new metric. (PR #4782)

• GeminiTTSService can now use the Gemini Developer API (google-genai) backend in addition to the existing Google Cloud backend. Pass api_key (or set GOOGLE_API_KEY) to authenticate with an API key instead of Google Cloud service-account credentials.

  • The backend is selected automatically: passing api_key opts into the GenAI backend, while credentials/credentials_path continue to use the Google Cloud backend. Use use_genai=True/False to force a backend explicitly. A GOOGLE_API_KEY present in the environment alone does not switch backends — it is only used once the GenAI backend is active.
  • New http_options parameter forwards google.genai.types.HttpOptions to the GenAI client.
  • The GenAI backend does not support prompt/style instructions or multi_speaker output; setting them logs a warning and they are ignored. Use the Google Cloud backend for those features. (PR #4787)

• Added a mode streaming parameter to AssemblyAISTTService, exposing AssemblyAI's U3 Pro latency/accuracy preset (min_latency, balanced, or max_accuracy). It trades transcription accuracy against turn-finalization latency and is only applicable to U3 Pro models, where the server defaults to balanced. (PR #4810)

• TaskManager can now be constructed with an event loop and an optional contextvars.Context (TaskManager(loop=..., context=...)), and creates all of its tasks within that context. You can pass a single task manager to WorkerRunner(task_manager=...) (and to individual workers) to share one loop and context across the runner and every worker, so context variables set in one task are visible to the others. (PR #4815)

• Added tunable parameters to the xAI TTS services: speed, optimize_streaming_latency, and text_normalization (plus with_timestamps on the WebSocket service). Set them via the service's Settings, e.g. XAITTSService.Settings(speed=1.1). (PR #4821)

• Added word-level timestamps to XAITTSService. When with_timestamps is enabled (now the default), xAI's per-character timing is converted into per-word TTSTextFrame objects, each carrying an accurate pts. Note that xAI delivers timestamps in coarse batches, so word frames are emitted in bursts; consumers should schedule off pts rather than arrival time. (PR #4821)

• Added a base_url parameter to TwilioFrameSerializer to configure the REST API host used for auto hang-up. By default the host is still derived from region/edge (unchanged behavior), but setting base_url lets you target a Twilio-API-compatible backend or a self-hosted server instead of api.twilio.com. (PR #4845)

• Added a first-class RTVI dtmf client message. Sending {type: "dtmf", data: {button: "1"}} makes the RTVIProcessor push an InputDTMFFrame downstream, the same path a telephony transport's keypress takes, so any bot with DTMF handling (e.g. a DTMFAggregator) reacts to it. One keypress per message. (PR #4849)

• Added DTMF keypress support to the behavioral evals. A scenario turn can now press keys with a dtmf: field (e.g. dtmf: "123#") instead of user:, sent as one RTVI dtmf message per key. A bot running a DTMFAggregator reacts to them as a transcription, so a dtmf turn can assert on user_transcription and response like a spoken turn. (PR #4849)

• Added built-in text transform functions for TTS voice formatting under pipecat.utils.text.transforms: strip_markdown, normalize_acronyms, expand_currency, expand_numbers, expand_percentages, expand_phone_numbers, expand_units, email_to_speech, normalize_dates, and replace_text. These can be composed individually via the text_transforms parameter on any TTSService, or used together via the new VoiceFormatter bundle.
