| Community | Hear every FlashBoss voice before you buy Every voice FlashBoss ships now has a sample on the website. One page, one real sentence from a real card per voice, read by the exact model and speed the game uses. Nothing recorded specially, nothing sweetened — if it sounds wrong there, it sounds wrong in the game. The two voice DLCs sit beside the voice they replace, saying the same sentence, so you can hear exactly what changes before you… | — | |

| Community | The cycle of updates is nearly finished In the last couple of weeks, FlashBoss has made a number of big structural improvements that open the way to new, more accurate Piper voices — such as the new Esperanto and Toki Pona pronunciation — along with a host of other improvements and bug fixes. Thank you for your patience through the busy update schedule. For English users, the biggest gains are the massively improved audio playback fu… | — | |

| Community | News: two voices come home — and a one-time audio refresh A one-time refresh, and why The next update — landing in the coming days — brings a change you'll hear immediately: Toki Pona and Esperanto now speak entirely through FlashBoss's native neural voice , the one trained specifically for Esperanto's sounds. Toki Pona had been borrowing a German voice, and it showed on the smallest words: vowels blurred, and w drifted toward v — sounds that voice wa… | — |
| In-game event | Toki Pona comes to FlashBoss - Included Free Toki Pona joins FlashBoss Today's update adds a fifth free pack to the base game. I have been heavily distracted making upgrades to the game and doing work on a linked project, intended for the Autumn Next Fest: Master Odiin's Universal Keyboard. Expect messages regarding progress, including a downloadable demo — it was meant to ship last week, so: very soon. The alternative voices have also be… | 24200260 |

| Major update | Built-in text-to-speech window. Live audio or save the file PRONOUNCE ANYTHING YOU CAN PASTE I could have made things easier for everybody by pregenerating audio files and shipping them with the game. You might wonder why I didn't, and finally, I can explain, by presenting the live, locally-generated text-to-speech generation tool, that ships free with FlashBoss. Hit Ctrl+P in FlashBoss to open the PiperTTS window, then paste or type any text and hear i… | 23766030 |

Please start new with a fresh profile. What's fixed: Steam Cloud saving. The major technical hurdle and the source of m… | — |
