Reading the tea leaves of Janet Yellen's every word

The Fed's monetary policy statement on Wednesday afternoon won't come with a press conference. Those Q&A sessions with the Fed chair happen in alternating meetings, so the next press conference will happen in September.

But if you're feeling lost without Fed Chair Janet Yellen live on camera, in what could be the last meeting before the Fed raises rates for the first time in nearly a decade, don't forget that Yellen has issued more than 25,000 words worth of Federal Open Market Committee press statements that might be worth a read. Market participants and financial journalists already obsess over every little word in the Fed's statements, so we broke down every single word Yellen has ever said in her official policy meeting interviews as well.

Specifically, we looked at every one of Yellen's statements and answers to questions in the six FOMC press conferences since she became chair in February 2014. (The questions themselves are excluded, along with a variety of common words—like "the," "so" and "it.")

Here are the most frequently spoken words by Yellen in total among her six press conferences.

The stakes are getting higher. According to internal projections it accidentally leaked last week, the Fed is likely to raise interest rates by the end of the year. The September meeting will feature a certain-to-be juicy press conference.

The Fed uses a variety of indicators—wages, inflation and unemployment—to gauge the overall state of the economy. Based on our analysis, Yellen's focus on "growth" has been ... growing. It's up 150 percent from her first meeting. That's wage growth, which has been relatively subdued, GDP growth, which the committee expects to be "moderate," and productivity growth, which has been weak.

Inflation, one of the Fed's prime directives, remains at the top of the list, while deflation is almost never mentioned. Yellen mentioned "deflation" only once, in December 2014.

"Oil" was also a one-hit wonder: Of the 19 times she uttered the word in total, 18 happened in December 2014. If you recall, that's when oil prices plummeted dramatically—about 30 percent—going into the December meeting. Yellen said those low energy prices would be good for the economy as a whole, while also keeping inflation numbers well below the Fed's 2 percent goal.

"Guidance" fell off the list as well. It was huge at first—with 22 mentions, and then down to just one in the latest meeting. While guidance has tanked, Yellen's new hot word is "data"—in June she said it 23 times, basically doubling its usage in each of her two previous appearances.

Yellen has made it clear that economic data would be central to the Fed's next move, as in: "The appropriate policy decision is going to be data dependent," and "we could see data in the months ahead that will justify the expectations that you see in the so-called dot plot." More often than not, Yellen's data is "unfolding" or "incoming," but sometimes it has also "evolved."

The Fed has also become far more concerned with taking "appropriate" action—the word more than doubled over the six meetings. "If economic conditions unfold in the way that most of my colleagues and I anticipate, we see it as appropriate to raise rates," she said. "It's not an ironclad guarantee, but we anticipate that that's something that will be appropriate later this year."

It appears the Fed chair has also grown more independent of the rest of her colleagues, as she barely references them anymore. Yellen's usage of the words "FOMC" or "committee" or "committees" (including "committee's" with the apostrophe), all saw big declines. Does that suggest she is taking a less group-oriented approach to her decision making?

And finally, Yellen appears to be getting fed up with everybody's repetitive questions. Her usage of the word "obviously" has skyrocketed, after only five mentions in the first five meetings, she said it 13 times in June.

If you explore the data yourself, you can find your own patterns in what Yellen has been saying. For those lonely on a written-only Fed day, this might get you through.

Correction: The Fed last raised rates nearly a decade ago. An earlier version misstated the time frame.
