Real-time speech-to-text (STT) and machine translation (MT) technologies are transforming how businesses overcome language barriers in global expansion, enabling multilingual customer support and unlocking international growth. These technologies allow agents to communicate in one language while customers hear another, and supervisors can monitor interactions regardless of the language spoken. This capability is particularly valuable for Business Process Outsourcing (BPO) and Contact Center as a Service (CCaaS) platforms, as it addresses challenges like talent limitations, quality assurance blind spots, and fragmented systems, which often hinder international expansion. By integrating real-time STT and MT into existing workflows, companies can reduce support costs, streamline global expansion, and maintain consistent performance across languages, enhancing customer satisfaction and scalability. Providers like Gladia offer advanced STT APIs, supporting over 100 languages and offering features such as real-time code-switching and fine-tuned language control, ensuring reliable performance even in challenging environments.
