If Google Home and CityFALCON cannot find the topic you're requesting, there are two likely possibilities.
Voice Processing Issues
We rely on Google's voice processing capabilities to listen to the audio of your voice, parse it, and send us a textual request. But sometimes Google is unable to understand a particular accent or a complex name or word. That means they cannot send us a sensible text request.
BNP Paribas is one example of a complex name. Some people might use the French pronunciation, some might use an Anglicised pronunciation, and some might mix them, like Anglicised for the letters but French for Paribas.
Newly minted words or emerging terms may not be recognised, either. Similar issues face jargon. Fintech comes to mind, since it is well-known within the industry but slowly integrating into the general public's lexicon. There may be medical, legal, or other terms that are common and possibly even used in products or headlines, but they're not widespread enough for reliable voice recognition.
If voice processing capabilities are causing the issue, we suggest you create a watchlist with a simple name, like My Stocks, on the desktop platform. Then you can always ask What are the top stories for My Stocks watchlist, which is relatively easy to parse and respond to.
Missing from Database Issues
There are millions of key personnel, companies, and ideas around the world. While we are trying to build our databases as quickly and comprehensively as possible, there will be missing topics in our earlier stages.
Fortunately, we track which voice requests lead to an error and add the term to our database. It may take a few days or a couple weeks before we fully integrate the term. If you have waited a little while and the term is still not part of our database, though, you can send us a message through the Contact Us popup on the bottom of every page or through our Contact Form.
