Introduction: Using Voice on the 9XR Pro

The 9XR Pro transmitter with its ersky9x firmware has the ability to announce warnings and

messages and play music using sound files stored on its micro SD card. The sound files that come

with the transmitter cover a wide range of basic situations, including the opening message, timer

count-down, switch positions, flight mode and telemetry readouts.

Additional or replacement voice files (.wav) may be downloaded from the Sound Pack Library

http://openrcforums.com/forum/viewforum.php?f=64 in many languages and accents, added to the

Voice folder on the Micro-SD card and programmed to be played by the transmitter at the

appropriate moment.

As well, you can make your own voice files to suit specific needs. The most obvious such need is

to create a file that will announce the name of a model when it is selected in the transmitter.

The basic principle of the voice feature of ersky9x is very simple. Some 200 or more short sound

clips are stored in .wav format on the transmitter’s Micro-SD card. Each voice file is named with a

dedicated four-digit number. So, for example, 0028.wav is the welcome message that plays when

the transmitter is turned on, while 0031.wav warns “Flight battery low!” and 0142 says “Flaps

down!” The firmware is already programmed to use some of these files, while others, through the

use of voice switches, can be set to play when certain conditions occur.

The audio format used for the voice files is mono 16 kHz WAV (Microsoft) signed 16 bit

PCM. Be sure the files you obtain or make use exactly this specification as there are other systems

which are incompatible with Ersky9x.

Part 1 of this manual deals with how to program the Ersky9x firmware on your 9XR Pro to use

voice files. Part 2 shows how to make your own voice files. Appendix A provides a list of voice file

numbers showing how some are already allocated to specific functions, while others are available

for custom use.

Part 1: Programming Audio on the 9XR Pro

This part of the guide explains how to use the ersky9x voice feature on the 9XR Pro.

Managing Voice Files on the Micro-SD Card

Voice files to be accessible to the transmitter programming must be stored in a folder called ‘Voice’

on the Micro-SD card. While almost any Micro-SD card can be used, 2GB is plenty for most

purposes.

Files can be added and managed by two methods. First, the Micro-USB card, which is located

behind the rubber cover on the bottom of the transmitter, can be removed and inserted into an

adapter which then fits into either a USB port or a card reader on your computer. Alternatively, the

transmitter can be started in ‘boot loader mode’ by holding the two horizontal trim switches towards

the centre while turning on. The transmitter can then be connected to a computer via USB cable.

For details see the manual 9XR Pro: Communicating with a Computer.

For tasks that may take considerable time, such as creating voice files, it may be better to use the first method rather than having your transmitter connected to a computer for extended periods. Be sure to make regular backups of the contents of the Micro-SD card on your computer. Voice File Organization Voice files for the 9XR Pro must have a file name in the form XXXX.wav, where XXXX means a four digit number starting with zero. So for example 0269.wav.
PAGE 3
Of course, you have to have a file that speaks the correct model name already loaded in the Voice folder on the Micro-SD card. If necessary, you can make the file yourself, as explained in Part 2 of this manual. Triggering a Voice Event A voice event could be changing the position of a switch; for example, when the flap switch is moved, the transmitter could announce “Flaps first position.” Or it could be a telemetry input, such as altitude, reported at set intervals.
PAGE 4
Both – Plays two files using only one switch. When the switch is turned ON, it might, for example, play file 0100.wav, and then when the switch is turned OFF, would play the next consecutive file, 0101.wav. Each file will play only once for a given pair of switch movements. Note that this option requires that the on and off audio files have consecutive numbers. Using this feature, you only have to program the “on” file number.
PAGE 5
Programming a Telemetry Event with a Switch This example uses the THR switch to trigger the announcement of a telemetry value (signal strength) and time. In the Custom Switch menu (page 8/13) shown below the left column has custom switches listed as ‘S1’ though ‘SO’ simply because there is not enough space for the three letter acronym used elsewhere (SW1 to SWO). On this menu you find the custom switches. In the left column, among all the logical statements, you will also find an option called Time.
PAGE 6
The options that interest us here are A (audio) and V (voice). These play a sound or voice clip to serve as an alarm: A – Triggers a pre-programmed audio alarm that sounds continuously, chosen in the right column from a list of available beeps, other sounds and vibrations. V - Triggers a voice file that will play continuously to provide a voice alarm.

Part 2: Making Your Own Voice Files While a ready-made voice file set is provided with the 9XR Pro, and others are available, you will probably want to make some of your own voice files, if only for such purposes as naming models. You have several options, depending on your preferences and equipment. You will need an audio editor which is user friendly. Audacity is recommended. It is free and is more than adequate. Search for ‘Audacity Audio Editor' and download the appropriate version for your computer.
PAGE 8
Now for a little more detail. There are many Mac voices and the default (Alex) is probably not what you want, as people prefer female voices. Go to System Preferences and open the Speech Preferences. Depending on the age of your Mac the number and quality of voices will vary. My iMac with OS 10.8 has six voices total all of good quality. You can also download 20 or so voices specifically for different languages, such as Italian.
PAGE 9
Where to now? You could make a .wav file from a piece of music or a siren and call that up when your allowable flight time has expired. Or you could record a message in your own voice to give you some colourful advice when an alarm condition is activated. What about if, when the throttle cut switch is activated, your radio says: ‘Great flight dude’? The possibilities are endless.
