The filming of Glasat na Bulgaria started on July, at bTV studios. Unlike previous seasons, audiences are reduced from its full capacity to maintain social distancing as a result of COVID-19 pandemic.
In this season, coaches complete their teams without a specific number of members. However, each one will be cut down to 14 contestants, on the last episode of the blinds. In addition to the season, each coach is given two blocks to use during the auditions.
The "final selection" follows right after the blind auditions. Coaches would finalize the number of artists on their team by choosing, randomly, 14 artists to proceed to the next stage. Artists chosen by their respective coach will proceed to the next round, the Battles, while the unselected ones will be eliminated.
The battles round begin airing on October 31. The battle advisers for this season are the following: Maria Ilieva (future coach in season 10-11) for Team Lubo, season 3 coach Atanas Penev for Team Ivan, Doni for Team Dara, Medi and Georgi Simeonov for Team Galena.
Each coach is entitled to one "steal" throughout the battles (as in season 6) to save a losing contestant. At the end of the battles, eight contestants (seven winning and one stolen artists) will remain on each team, advancing through to the Knockouts.
The Knockouts round begins airing on November 21. Ishtar is the Mega mentor for all teams in this phase. Each team has a total of eight contestants, and three will be chosen by their coach to go through to the Live shows. During this round, Galena has only seven artists to perform due to Galya Georgieva's withdrawal from the show.
Cross Battles were broadcast on December 5. In this round, an artist would be sent by his or her coach to compete against an artist from another team. The selection of the artists and their order of appearance were all decided by their respective coaches, and all of them were done without the knowledge of the opposing coach. Therefore, the battle pairings were completely random, and would only be revealed when the coaches appeared with their selected artist on stage. This is the first time the Bulgarian version has had this phase.
As the Cross Battles are broadcast live the results of the battle will be determined by public vote in real-time. Public votes will be done only during the airing of the episode. After this round, six artists will be remaining to move on in the Grand Final. It is the first time the series has a final with six finalists.
With the elimination of Rashed, Ivanov, and Zdravkovic, Lubo Kirov no longer has any artists remaining on his team. For the first time in the show's history, a coach's team does not have any artists in the grand finale.
The final was divided into three rounds. First, the six finalists performed with a guest, and then the sixth and fifth places were announced. In the second round, the four finalists remaining performed alone and the fourth and third places were, then, revealed. Finally, the Top 2 performed alone again, followed by the winner announcement.
