In addition, a gala event will be held on October 30 to celebrate the achievements of players on the Tour during the year.
Speaking to the media following the launch at the ArtScience Musem at Marina Bay Sands, last year's runner-up Simona Halep of Romania recalled her experience of Singapore in 2014.
"I felt like I was home because I had many fans in the crowd supporting me. They gave me power to compete very well at a high level. This place (Singapore) means a lot for me," the world number three said.
The event organisers also revealed a new programme called "Advantage Singapore", which will enable fans to learn various training regimes and other aspects of the sport from the likes of Serena Williams and Billie Jean King.
"Through this initiative, girls from the next generation are able to compete for a chance to play alongside the best in Singapore and aspire one day to play in the WTA Finals themselves. Singapore is attracting the eyes of the world," Melissa Pine, vice-president of WTA Asia-Pacific and tournament director of the WTA Finals, said of the programme.
