Enabling streaming allows the transcription to happen in **real time**, leading to faster and more natural conversations. > ⚠️ **Important:** Most providers support **streaming mode**, which is preferred for smooth, low-latency conversations. > The only exception is **Faster-Whisper**, which operates in **non-streaming mode**. Be cautious when changing this setting if using Faster-Whisper. *** ## 🔊 Text to Speech (TTS) The **TTS** engine converts the assistant’s text responses into natural-sounding speech. * Choose from a wide variety of **human-like voices** across different providers. * You can configure the **voice style, gender, and accent** depending on the provider. * There is also a **streaming mode** option, allowing speech to begin playback as it’s generated — improving response time and interactivity. > 💡 **Recommendation:** Keep TTS in **streaming mode** for faster, more natural responses during real-time calls.
