Frequently Asked Questions

What is RaceVoice?

Simply described, RaceVoice collects on-track data from your dashboard and provides real-time on-track driver performance and engine monitoring feedback using speech synthesis.

Information such as when to UpShift can be announced, similar to a shift-light function but with 100% “heads-up” so you don’t need to look at your dashboard. Corner segment information such as minimum speed through a corner, entry speed, turn-in speed, exit speed can be announced. Vehicle dynamics such as wheel-lock up and brake threshold “tone” feedback can be enabled. RaceVoice can also announce rolling MPH, max linear-g force, and rolling (or corner selected) lateral-g force to help you use the most of your available grip.

RaceVoice can also monitor critical engine parameters such as high temperature, low-oil pressure, and low battery. If these conditions occur, RaceVoice will begin announcing an temperature, oil, and battery fault. This is an additional layer of protection that might help prevent engine damage and possibly save your racing weekend and thousands of dollars in repairs.

How do I know what In-Car Audio style I have?

If you currently do not have a radio in your racecar, then our standard earbuds are the best choice for your installation.

We provide radio cables for IMSA and NASCAR style wiring. See the examples below.

Nascar Style Y-Audio Cable

IMSA style Y-Audio cable

How can I tell the difference between IMSA/Nascar/Stilo connectors?

A Nascar style connector has three conductive bands and two black insulator bands. The size/shape is similar to a headphone set for a record player (remember those??)

An IMSA style connector has four conductive bands and three black insulator bands.

A Stilo connector has four conductive bands and three black insulator bands, just like the IMSA but the wiring is completely different. If have a Stilo helmet, you may have a short male-to-male cable with your Stilo. This male-to-male cable is used to connect a Stilo helmet to an IMSA/Nascar wiring system in your race car. Our IMSA and Nascar cables are compatible with Stilo’s of this configuration, provided you connect our cable to the IMSA or Nascar side of the male-to-male Stilo cable.

Is RaceVoice Waterproof?

RaceVoice is water resistant. The recommended mounting should have it placed in the “upright” position so the volume connector is facing up. This will help prevent water from getting inside. The internals of the unit are conformally coated (basically a urethane finish over all of the circuit board) to seal it from water/humidity/chemicals.

Does RaceVoice record or log data?

Currently RaceVoice is not doing any data acquisition, so it is reporting what you did on track while you are on track.

Will RaceVoice need to be setup from scratch for each track?

Not from scratch, the engine/shift-points/etc parameters generally do not need to change. However when you get to a new track, you will pick the track from the software (RaceVoice Studio) and then configure tell RaceVoice what corners/speeds/etc you want to work on and/or get feedback on. RaceVoice Studio software will remember your settings for the track. So if you are working on “turn 1” it will remember it between weekends and your current speed/performance selections for the track will be saved on your PC.

What software is used with RaceVoice?

Our software is RaceVoice Studio, which runs on a Windows 7/8/10 PC (also a Mac using Parallels). A USB connection is used to link the PC to RaceVoice and download map/setup data.

How does RaceVoice get its data?

RaceVoice derives all data from the dashboard in the car. A configuration file is loaded into the dashboard to tell it to send data, using CANBus, to the unit. RaceVoice needs to be connected to a CANBus link (not used by the ECU) such as CAN2 on an Aim or MoTeC. We provide configuration files so you can setup the dashboard to talk to RaceVoice. You can also send your existing dashboard configuration file to support@racevoice.com and we can add the RaceVoice setup for you. RaceVoice supports CANBus rates of 125Kb, 250Kb, 500Kb, and 1Mb/s.

I’ve installed my RaceVoice but I’m not hearing anything?

When power is applied to RaceVoice, it will speak an announcement phrase such as “RaceVoice Version XXXXX” to announce its firmware version number. Approximately 20 seconds after power-up, it will also announce the current temperature, oil pressure, and voltage as transmitted by the dashboard.

If you aren’t hearing anything, the first step would be to directly plug earbuds into the 3.5mm audio output connector on RaceVoice and ensure that you are hearing the announcement. Once confirmed, make sure that you have the Nascar/Imsa y-cable connected in the right location. If you are using a Stilo helmet, make sure that the y-cable is connected to the Nascar/Stilo side of the male-to-male cable that connects to your Stilo. Also, remember that the Stilo male-to-male cable (even though it has similar connectors on both side) is directional. One side is specific for the helmet and the other side is specific for the IMSA or Nascar wiring side.

If you are hearing the phrase “No Connection”, then this means RaceVoice is working but it is not getting any data from your dashboard. Ensure that you have a configuration file on your dashboard’s CANBus output so that proper data is sent to RaceVoice.

How do I adjust the volume?

RaceVoice provides two levels of volume. The first level is the knob on the unit. This functions as a traditional volume control, where full clockwise rotation is maximum volume. The default audio power for RaceVoice is calibrated for our earbuds. If you are using different earbuds OR a Stilo helmet, you may need additional volume. RaceVoice Studio provides a digital volume adjustment under the “Advanced–>Voice Settings” menu. This menu can be used to further increase the audio power of RaceVoice.

The “Advanced–>Voice Settings” menu also provides a “pitch” control where you can adjust the tone of the speech synthesized voice. The voice can be adjusted approximately one octave higher or lower. This can be helpful to change the tone of the voice so that it is not in the same tonal range as the exhaust of the race car. Adjusting the tone can have a similar effect of providing more volume because the synthesized voice will be in a different tone/frequency range. Your ear may also be more sensitive to one tone range VS. another as well.
