🤖 I have created a release *beep* *boop* --- ## [7.8.1](v7.8.0...v7.8.1) (2026-09-03) ### Bug Fixes * **TextBuilder:** `ssml_to_deepgram()` now preserves a `<phoneme>` pronunciation when its valid `ph` and `alphabet` attributes appear in either order. ([#741](#741)) ([7fd4b63](7fd4b63)) * **Credentials:** Explicitly passing `api_key=None` continues to disable ambient `DEEPGRAM_API_KEY` lookup, which is important for multi-tenant and test environments. ([#778](#778)) ([e675990](e675990)) * **Credentials:** `DeepgramClient()` and `AsyncDeepgramClient()` now resolve `DEEPGRAM_API_KEY` when constructed, so `load_dotenv()` can run after importing the SDK. Closes [#734](#734). ([#767](#767)) ([ec362ec](ec362ec)) * **Custom transports:** Speak V2 WebSocket connections now honor `transport_factory`, matching the routing behavior of other WebSocket APIs for proxies, test doubles, and custom-hosted transports. ([#766](#766)) ([0980663](0980663)) ### Documentation * **Transcription:** Clarified that Nova-3 assumes English when `language` is omitted; non-English and multilingual audio require an explicit language such as `fr` or `multi`. ([#771](#771)) ([4574337](4574337)) * **Examples:** Added Listen V1 live microphone transcription with optional `sounddevice`, device selection, bounded audio buffering, transcript output, and clean Ctrl-C shutdown. ([#780](#780)) ([08f0471](08f0471)) * **Examples:** Added a resilient Listen V1 live transcription pattern with exponential backoff, reconnect-aware audio buffering, timestamp continuity, and clean shutdown. ([#776](#776)) ([96b2d11](96b2d11)) * **Examples:** Added an application-owned Voice Agent session recorder that serializes received transcripts, function calls, and latency reports as JSON while leaving consent, redaction, retention, and storage policy to the application. Closes [#775](#775). ([#781](#781)) ([30ad152](30ad152)) * **Text-to-Speech:** Corrected streaming synthesis snippets to iterate the response byte chunks instead of accessing a nonexistent `.stream` attribute.

The text-to-speech snippet in the README called
response.stream.getvalue(), butclient.speak.v1.audio.generate()returns anIterator[bytes], so running it as written raisesAttributeError: 'generator' object has no attribute 'stream'. I changed the snippet to iterate the response and write each chunk, and applied the same correction to the identical snippet in the v3 to v5 migration guide. Fixes #638.I pushed this to my fork first and the project's own CI workflows pass on the commit.
