However, there are a number of open source TTS engines, and even Google TTS no longer requires "high quality" voices. Here is an open source TTS engine: http://espeak.sourceforge.net/index.html And here is a sample audio file created by that free TTS engine: http://espeak.sourceforge.net/samples/raven.ogg It has a linux and a windows version -- perhaps it could run on older kindles that do not already have TTS buried in their menu system. And there are even more open source TTS choices on github (some of which I published links to in the past). Considering that there are software-only TTS systems that work just fine on Arduinos, I think we could get something doing TTS, even on a "lowly" K1 (which has a built-in MP3 player). So If you want "TTS" on a K1, load the audiobook MP3 on it, start the player, and open the book to follow along, eh? Last edited by geekmaster; 05-21-2016 at 04:43 PM. |

eSpeak is certainly better than Hawkings ancient TTS system, but I can't imagine listening to books read by that system. I tested Open Source TTS voices some time ago, because one of my machines runs Linux, but there really isn't any free TTS voice that comes close to the Ivona voices and other commercial TTS products. In that respect Open Source is utterly underdeveloped and many visually impaired Linux computer users eventually switched to OS X, because TTS is built into the OS and each version comes with number of high quality voices in a couple of different languages. |

Except it only reads the error message popup about missing voice files, and where to go download them. |

PHP Code:
When that script was run from KUAL (after my PW3 stopped complaining about the missing voice file), with a headset and microphone inserted into the USB dongle, it created this log file: PHP Code:
When I run twobob's "Balsamic" demo (also from a KUAL extension), it does play audio (for awhile, before it segfaults on my PW3), but recording seems to not work, unless I need extra parameters on the "arecord" command... EDIT: Though as you can see, "aplay" was complaining about "no sound card" before it whined about a missing sound file. So twoboob's Balsamic demo MUST be accessing the sound hardware differently than arecord and aplay, because his demo works. So perhaps we CAN get microphone input to work, using whatever "trick" twobob used to get sound output working on these USB dongles. Last edited by geekmaster; 06-01-2016 at 01:35 PM. |

It has been years since I successfully compiled an app that needs ALSA. If I can compile my new gmplay-2.0 (with sound), then I could also code up something to test the USB microphone input. Alas, no luck just yet... Need get some headers and libs and stuff in the right place...
There are probably some hints in some twobob thread or post *somewhere*. I wonder if they got into the master index? Time to do some searches (after I finish building my replacement linux box -- the old linux mint VM I was using is getting a bit to "wonky" for my liking -- especially after installing glib-2.0 as needed for some proggy that refused to build ANYWAY). Just need to decide between Arch and Gentoo, eh? Anyway, new linux box (not a VM), then get ALSA compiles working, then test USB audio input again...

Interesting that Amazon have just announced a new model which does TTS via Bluetooth.

It also makes me curious if it will work with generic bluetooth phone headsets and bluetooth speakers. I am hopeful though because it already supports generic USB sound dongles (which I have tested personally on my PW3). |

And if they added an on-board soundcard chip, they might as well add regular headphone sockets. |

An onboard sound chip is only needed to create onboard sound, for onboard sound devices (speakers or headset jack), like in the K5. Last edited by geekmaster; 06-23-2016 at 08:52 AM. |

But if I connect a Bluetooh headset with a smartphone or tablet won't the devices need to perform an audio-to-digital conversion first with an analog-to-digital converter before they can transmit the BT packets?
And unless the Kindle TTS module is capable of generating BT-compatible audio data packets, the Kindle would at least need an ADC. |
