### Gaps in Existing VR Language Learning Research  
Incorporating virtual reality (VR) into the domain of language pedagogy has undoubtedly exhibited promising outcomes. However, discerning and acknowledging the lacunae and constraints inherent in the prevailing research landscape is crucial. A proactive approach toward these gaps can set the stage for more exhaustive research endeavors and refined VR methodologies in the subsequent phases.  
Extended Scope of Research: Most studies centered around VR in language education delve into brief interventions. A pressing requirement emerges for longitudinal examinations that scrutinize the persistent influences of VR on linguistic adeptness over prolonged durations.  
Standardizing Success Indicators: The benchmarks deployed to gauge the efficacy of VR-centric language learning tools oscillate across diverse studies. Instituting a standardized set of metrics can yield a more lucid understanding of VR's tangible contributions to linguistic mastery.  
Broadening Linguistic Horizons: Although an array of VR tools caters to predominant languages such as English, Spanish, and Mandarin, there must be more platforms for less mainstream languages. Widening this spectrum can render VR-driven language education more encompassing.  
Technological Inclusivity: Elite VR configurations carry a hefty price tag, potentially placing them out of reach for a broad learner demographic. Investigating the potential of frugal VR systems in facilitating language acquisition can democratize access to this innovative tech.

Table 1: Key features of effective virtual reality (VR) language learning.  
Harmonizing Tech and Pedagogy: Certain research endeavors bear an excessive tilt toward VR's technological facets, inadvertently overshadowing the pedagogical dynamics. An equilibrium that marries pedagogical tenets with tech strides is paramount.  
Empowering the Learner: Amid VR's captivating ambiance, there is a conspicuous research void regarding the learners' autonomous journey and self-direction within these realms.  
Symbiosis with Conventional Pedagogy: The interplay between VR and traditional classroom-centric language instruction remains relatively uncharted. Probing into hybrid learning models amalgamating VR could shed light on enhancing the holistic language learning paradigm.  
Navigating Cognitive Intensity: The encompassing nature of VR might, at times, thrust learners, especially novices, into a cognitive whirlwind. Developing strategies to curtail and navigate this cognitive inundation can refine the learning trajectory.  
To encapsulate, the extant research, though insightful, warrants augmentation to harness VR's potential in language pedagogy. As we tread forward in VR-infused language instruction, it is pivotal for scholars, pedagogues, and tech innovators to engage in collaborative endeavors. This collaboration maximizes the potential of the technological framework, enhancing educational experiences for learners worldwide.
