How to make Your own sound files to Jeti?
In basic it’s easy. Drop a file to Jeti and select it. In practice there’s a few pointers on should take in to consideration.
First of all, not any soundfile works. Second of all, it Would be cool if all the sounds would sound pretty much the same, this is of course a matter of opinion…
Update: You can also get your sound-files from RC-Thoughts! Just go here to get the files! Use this guide to do editing if You need to.
The original sounds (speech) in Jeti is from Ivona Text-To-Speech, You can use their webpage to generate Your own sounds that sound exactly like Jeti’s original. (The speech profile in english is “English, American, Jennifer”). The Ivona page is http://www.ivona.com/en/.
Since AT&T Text-To-Speech is now down (forever apparently) this guide is now updated to use Ivona.
Unfortunately Ivona does not allow us to save the spoken text to file. So we need to record it with Audacity. So. let’s download Audacity, a free and very good sound-editor from http://audacityteam.org/ (do NOT download anymore from sourgeforce!) and install it.
After starting Audacity it looks like this:
First we need to make the Audacity to record the voice played by Ivona. Select your recording input as “Microsoft Sound Mapper – Input” as in picture:
Note: Set recording volume as low as possible = 0.00:
Now go to Ivona and play with commas, exclamation mark, capital letters and so on to get the pronunciation to what you want. when you’re satisfied leave the settings as they are and switch to audacity and start recording by pressing the record-button:
Jump back to your browser and Ivona, press the “Play”-button:
Go back to audacity and immediately press the “Stop”-button:
Now Audacity should something like this:
You’ll see there’s extra space (silence) in the beginning and in the end of file. Also the dynamic (“volumerange”) is pretty low, it’s not reaching to 1.0 on the vertical axis. But let’s fix the silence first.
Select with mouse the area you wan’t to remove, click on the center-line and drag the mouse until You have selected the area:
Simply press delete (DEL) button. Do the same to the end.
After that it’s time to maximize the dynamic range (volume) of the sound-file, let do something called normalization. First press CTRL-A to select the whole clip:
Then in the menu go to “Effect” -> “Normalize”:
The default maximum amplitude is -1.0 dB, I usually change this to -0,5 dB. Press the preview, if there’s any distortion at all lower the maximum amplitude to for example -1,5 dB and preview again. After it sounds good press ok.
Your file is now normalized to a larger dynamic area, it sound’s “louder”, this can also be seen in the waveform, it’s “taller”:
Now we need to save the file, go to “File” -> “Export audio”, select the file type to “WAV (Microsoft) Signed 16 bit PCM” and click save.
This is important! Jeti needs (want’s) the metadata to be stripped! So make sure there is nothing in the following screen before clicking the ok-button!
So, now You have the audio-file on Your computer. Move it to Your Jeti the usual way. Drop the file to right directory:
And use it where ever You wan’t to :)
Sometimes it just is easy :)
