Businesses are increasingly adopting speech-to-text (STT) technology to enhance customer experiences, but they face a critical decision about whether to develop an in-house solution or outsource to an API provider. The decision involves evaluating factors such as technical expertise, customization requirements, scalability, cost, and resource allocation. Open-source solutions like Whisper and Kaldi offer control and customization but entail complex maintenance and high total costs of ownership. Conversely, API providers offer quick deployment, scalability, and advanced features with less operational complexity, making them suitable for businesses lacking in-house expertise or needing rapid market entry. The choice depends on a company's specific needs, including transcription volume, customization demands, and resource availability, with many opting to outsource due to the fast pace of innovation in AI technology.
