What options exist for spoken audio alerts of traffic?
What options are available for adding spoken audio alerts of ADS-B traffic?
?Traffic: 10 O?Clock, High or Low or Same Altitude, 2 miles.? - that sort of alert is what I am looking for.
I have or will have the following equipment:
430W, 496, PMA8000BT audio panel, Navworx ADS600-EXP, Asus TF700 with Anywhere map (no ads-b functionality)
I understand a GDL 88 will do it, but it is about 5k.
I believe I read that foreflight / stratus will do it, but I do not use foreflight or an ipad.
A GDL 39 would be a reasonable cost addition. I read that a GDL 39 (along with my 496) will do it, but from the Garmin website it doesn't sound like the complete alert including position and relative altitude. This is what the Garmin website says about the GDL 39 traffic: "Spoken audio alerts announce ?Traffic, Traffic? to get you looking right away."
So, can anyone confirm what the GDL 39 actually does in terms of audio alert? What other options are there?

Garmin does this very well and it is quite useful to get you looking in the correct direction quickly. I have flown with poition call outs (Garmin). It is really effective.
I made a suggestion on the Dynon forum, that Dynon use the position call out which seemed to have gone with little fanfare so they likely won't implement this.
I think the traffic, traffic is a good (better than nothing) but the next thing after hearing that is one tends to look at the display to determine where to look. That is heads inside before heads out. With the position call out your eyes can go directly outside to the correct place. Kudos Garmin.
However, like all aural alerts more can be a problem when in rapid fire communications with ATC.

More than 2 years have passed... Surely some offer this by now.
What ads-b options offer spoken audio alerts?

I believe this is one of the things the Stratux team is working on... The RasPi it's based on has an audio jack, and the traffic data is there. All someone has to do is code up something to convert the data into an audio stream, and you can plug the audio into your audio panel.

I wasn?t aware Stratux was investigation the feature of audio based traffic alerts with position information.
Indeed ... - all of the requisite data is there on Stratux configurations with an integrated GPS
- there is a line-level audio out capability on the Raspbarry Pi 3
- the necessary vocabulary is very minimal
- piecing together the audio fragments into a message would be straight forward

I believe the audio is a function of the application that is displaying the traffic ( Foreflight, Pilot, etc.) and not a function of the instrument that is receiving the data ( i.e. GDL-39, GDL-88, etc.). Having said that I can verify that using a GDL-39 feeding a Garmin 696 and, lately, Garmin GDU470, those instruments are indeed only alerting "Traffic, Traffic, Traffic". On the other hand, Foreflight, on an Ipad using the same GDL-39 feed at the same time, is alerting "Traffic 2 O'Clock - 2 miles - 400ft below".
Sounds like maybe you should rethink your idea of NOT using an Ipad with Foreflight.

ForeFlight offers traffic alerts that work very well. I have a Garmin GMA 245 audio panel which receives Bluetooth data. The ForeFlight traffic alerts on my iPad transmit to the audio panel which outputs through the music channel.

Not to derail your thread
...but when I ponder what "breakthrough" developments might come next in the experimental avionics world - beyond mere refinements to what we have off the shelf now - all I can think of is 1) wider implementation of HUD display technology, and 2) a shift to voice as both input and output medium of choice. (Some would add FADEC).
Avionics developers who want to stay on the leading edge will have to enable us to tune frequencies, swap screens, engage autopilots, set flaps, initiate TO/GA, etc using voice commands the way we presently address Siri and Alexa. In the same way, we will come to expect aural AoA cues and voice callouts of traffic, V-speeds, engine monitoring anomalies and so forth.
"Hickman Five Thousand, engage autopilot."
"Autopilot engaged."
"Set altitude hold."
"Altitude hold at 4,500 feet engaged. Please trim nose up."
a short while later...
Traffic alert, 6: o'clock 1 mile. 500 feet above. N666BK. Russian has a deflection-firing solution."
"$h!#"
"I'm sorry, Stormy, I didn't quite get that... Would you like me to fly for awhile and get you inside his OODA loop?"
That's my future vision. I think everyone who remains a player in experimental avionics will offer voice-recognition IN and synthesized voice OUT sooner than later. This may begin with traffic announcements, but it will end with a full voice I/O suite, making the manipulation of our EFIS screens in turbulence or a smoke-filled cockpit/bird strike blood-in-your-eyes scenario a whole lot easier.

You might want to re-consider Foreflight. It will annunciate alerts on your iPad/iPhone, and you can couple those to a Bluetooth device of your choice, or hard wire them to your audio panel. Let's see, besides traffic you get runway alerts while taxiing, a 500' alert to remind you to check gear down, and if you have an iPad with a pressure sensor, you get cabin altitude alerts.

This is an interesting observation; I had primarily thought of it as being related to the unit receiving the data, generating an audio alert and sending it to the audio panel. Indeed I just looked up the gdl88 and it appears to do just that.
The way you describe foreflights audio alert is just what I am looking for. A couple issues will likely preclude me for going that route. While I completely understand a companies desire to limit their software to 1 platform, I prefer the other platform and have chosen to not reward the company that chooses to limit their market. The second issue is with Apple for 2 reasons. First Apple is proprietary and I try to not reward companies who choose that business model. The second reason is the one time I did buy an ipad to run a particular aviation glide to airport software I got burned. The aviation app which cost about $100 released an update shortly after I purchased it that disabled the software if I didn't pay a monthly subscription (of about $20/month I think). This seemed unethical and tantamount to ransomware. The software company refused refund yet continued to peddle their software in the apple store. Apple in my view was complicit as Apple denied my request for refund and allowed the company to continue sales.

I have long thought this too.

Don't think I can bring myself to do it John. See above rant, or I mean explanation, regarding my history with an i-thing.
