poor marketing feedback from western territories. Later, during an interview involving Hearts R and Tales of Xillia 2, series producer Hideo Baba stated that while the game was never intended for localization, if Hearts R sold well, a localization could be considered. Audio Voice acting in Tempest was restricted to battles. Dissatisfied with this approach, the developers wanted to have full voice acting for Innocence while keeping as many planned features in the game as possible. After some trial and error, and on the verge of scrapping voice acting altogether, the team used CRI Middleware's Kyuseishu Sound Streamer compression algorithm to fit the voice acting into the game alongside the other features. The team first learned of the algorithm in May 2006, when the first prototype of Innocence had already been built. The inclusion of the algorithm forced the team to scrap elements of the first build and restart development. The new prototype was completed in November 2006. The predicted amount of voice recording was estimated at 120 minutes. The final product included 40 minutes more than that. According to Ōdate, approximately 70-80% percent of the main scenario was voiced, with the rest of the game's dialogue using text due to hardware limitations. The voice work took up one gigabit of storage space on the DS card. For Innocence R, the voice acting was re-recorded, with the entire main scenario being voiced. This enabled minor changes to character portrayals, as in the case of Kimura when she was redoing Luca's lines: according to her, she worked to inject a little more energy into Luca's voice. For the two new characters, the team created a fictional language called the "Triverse Language", which the characters' actors sometimes had trouble speaking. Music The music for Innocence was composed by Kazuhiro Nakamura, who had previously worked on the Time Crisis and Tekken series. The tracks were arranged with the help of Taisuke Sawachika. For his work on the game, Nakamura chose a different style of music from that of Motoi Sakuraba, who had handled the majority of previous Tales titles: he used ethnic music to distinguish it from earlier games. For the battle music, he used Sakuraba's battle compositions as a reference while keeping to his own style. The remixed and additional music for Innocence R was again handled and composed by Nakamura. The theme song for Innocence, "Follow the Nightingale", was created and
