Abstract
A contract is a formal agreement that may be either written or verbal. While generally less formal, agreements can evolve into contracts once all essential legal elements are present, making agreements a precursor to formal contracts. One of the key components of a legally binding contract is consideration. In India, the statutory provisions outlined in the Indian Contract Act provide the legal framework for contract formation. This paper, however, deals with oral agreements. An oral agreement is legally binding, but in the event of a disagreement, its enforceability is called into doubt and frequently results in a “he said, she said” scenario. To address this issue and enhance the admissibility of oral agreements in the Indian judiciary, an automated system is proposed that converts oral agreements into written contracts using speaker recognition, speech-to-text conversion, and blockchain technology. The system identifies the speaker from the audio recording through speaker recognition algorithms. OpenAI’s Whisper module is employed for speech-to-text conversion, enabling the transcription of the oral agreement into written form. A digital signature is then generated using the SHA-256 hashing algorithm, where the hash of the agreement is encrypted with the speaker’s private key to ensure authenticity and integrity. Finally, the use of blockchain technology ensures that the written agreement is secure, tamper-proof, and immutable.
