Before even looking at this campaign... when you said $180 USD now for crowd-funding for a $200 USD retail cost I immediately thought, "Why be on the burning edge to save $20?". Knowing how risky IndieGogo campaigns tend to be, I'd hold back my money and gladly pay $20 more when I have something tangible, reviewed and with a money-back guarantee from a retailer. Just not enough of an advantage to back this, in my books, even if it does pan out to be an awesome real product.
EDIT: Ok, I looked at the campaign page, it's 33% off of what is now $199 as the base price since all Early Birds have sold out. Doing the math.... so retail $300, so 33% off means a third off... brings it to $200. Is that right? Worth $100 savings to jump on this device which is ALREADY way over-funded (so it is happening, no need to feel guilty that not giving your money caused the campaign to fail). At this point, any further money is only people "buying" the product because they want a discount. If you bought before they reached goal, you could argue your money is seeding the project and needed to help it achieve goal. But now, it's just because people want to save $100.... assuming it is made into a final product that is available, you should be able to eventually pick one up.
Let's see.....
1. Input sound (from phone or earpiece?)... then Siri or Google translates speech to text
2. Text translation (google translate or other API's) language 1 to language 2
3. Text to speech synthesizer (Google API) to send sound to earbud via BlueTooth
All bundled into a nice package. Truth is, the *ENTIRE* thing can be done with your phone.... the earpiece is a misdirected fluff..... It is all APP-BASED. The earpiece would simply be a blutooth device with possibly integrated microphone (although that would be a bad place to put it). Why do you need it? Just make an APP that does all of it.
As far as pictures of Arduinos and other boards next to the earpiece... It's all B.S., The entire system is based on your phone and cloud-based connection, using existing speech to text, translation and text to speech services. They just chained the inputs and outputs. 3 separate steps, done in their software, one after the other, sequentially, using cloud-based services or a local software-based speech synthesizer API.
I SEE WHAT IS GOING ON HERE:
With over $1,000,000 they could make the the software.... But they can't SELL you software for $200-300 a piece. Instead, they "bundle" in the earpieces so you feel there is something more tangible you are buying. And all that "fluff" showing PCB's and circuits.... That's all marketing B.S. because they even say in the video it is all done in the app and the earpieces are likely simply bluetooth devices which can be obtained from a Chinese OEM under their design specs to look different. As far as the latency... I'd be more concerned about that, but even if it was fast, I'd like to know how people are willing to pay $200-300 for an app that does this.
Questions:
Why do they need so much processing in the earpiece? If everything is being done by the phone? Earpiece 1 and Earpiece 2 would simply be BlueTooth linked to the phone. How would the app or earpieces track who is saying what, to channel the output translated speech to the other earpiece? Would it compare microphone loudness levels to determine who is doing the speaking, then push the translated output to the other earpiece, and vice versa? So if microphone 1 on earpiece 1 is louder signal than microphone 2 on earpiece 2, then person 1 is doing the talking, and the output would be sent by the app to earpiece 2. If microphone 2 is louder than microphone 1, app assumes it is person 2 doing the talking and speech gets sent to earpiece 1 after translation. Or, the app most likely allows you to set the languages of the 2 speakers and who wears what earpiece (1 or 2) and that information alone is enough to do it.... NO need to "compare" audio levels between mics. So what is all the extra hardware on the earpieces for, and the ARM processor, and everything else?
