OpenAI debuts Whisper API for speech-to-text transcription and translation

To coincide with the rollout of the ChatGPT API, OpenAI at present launched the Whisper API, a hosted model of the open supply Whisper speech-to-text mannequin that the corporate launched in September.

Priced at $0.006 per minute, Whisper is an computerized speech recognition system that OpenAI claims permits “strong” transcription in a number of languages in addition to translation from these languages into English. It takes information in a wide range of codecs, together with M4A, MP3, MP4, MPEG, MPGA, WAV and WEBM.

Numerous organizations have developed extremely succesful speech recognition programs, which sit on the core of software program and companies from tech giants like Google, Amazon and Meta. However what makes Whisper totally different is that it was skilled on 680,000 hours of multilingual and “multitask” information collected from the online, in line with OpenAI president and chairman Greg Brockman, which result in improved recognition of distinctive accents, background noise and technical jargon.

“We launched a mannequin, however that really was not sufficient to trigger the entire developer ecosystem to construct round it,” Brockman mentioned in a video name with ClassyBuzz yesterday afternoon. “The Whisper API is similar massive mannequin you could get open supply, however we’ve optimized to the intense. It’s a lot, a lot sooner and extraordinarily handy.”


To Brockman’s level, there’s a lot in the best way of obstacles relating to enterprises adopting voice transcription expertise. Based on a 2020 Statista survey, firms cite accuracy, accent- or dialect-related recognition points and price as the highest causes they haven’t embraced tech like tech-to-speech.

Whisper has its limitations, although — notably within the space of “next-word” prediction. As a result of the system was skilled on a considerable amount of noisy information, OpenAI cautions that Whisper would possibly embody phrases in its transcriptions that weren’t truly spoken — presumably as a result of it’s each making an attempt to foretell the subsequent phrase in audio and transcribe the audio recording itself. Furthermore, Whisper doesn’t carry out equally nicely throughout languages, affected by a better error charge relating to audio system of languages that aren’t well-represented within the coaching information.

That final bit is nothing new to the world of speech recognition, sadly. Biases have lengthy plagued even one of the best programs, with a 2020 Stanford study discovering programs from Amazon, Apple, Google, IBM and Microsoft made far fewer errors — about 19% — with customers who’re white than with customers who’re Black.

Regardless of this, OpenAI sees Whisper’s transcription capabilities getting used to enhance present apps, companies, merchandise and instruments. Already, AI-powered language studying app Communicate is utilizing the Whisper API to energy a brand new in-app digital talking companion.

If OpenAI can break into the speech-to-text market in a significant manner, it may very well be fairly worthwhile for the Microsoft-backed firm. According to at least one report, the phase may very well be value $5.4 billion by 2026, up from $2.2 billion in 2021.

“Our image is that we actually wish to be this common intelligence,” Brockman mentioned. “We actually wish to, very flexibly, be capable of absorb no matter sort of information you could have — no matter sort of process you wish to accomplish — and be a power multiplier on that focus.”
