The act of transcription from spoken word to text is incredibly important for ease of communication, file sharing, summarizing speech intent, deciphering languages, accents and clarifying speech dialects, and perhaps most importantly, providing accessibility to those with hearing disabilities.
Developers wishing to improve communication within their applications should consider adding transcription services to them. To do this, they need Transcription APIs.
What is a Transcription API?
A Transcription API is an Application Programming Interface that enables developers to enhance their own applications with transcription services.
The best place to locate these APIs is in the Transcription category of the ProgrammableWeb API directory. In this article, we provide details of the 9 most popular Transcription APIs, based on web page visits to ProgrammableWeb.
1. Google Cloud Speech-to-Text API
The Google Cloud Speech-to-Text APITrack this API is a speech recognition system that applies neural network models for accuracy. The Speech API supports 80 languages and can transcribe text, and enable voice commands. This API features speech adaptation (recognizes domain-specific terms and rare words), model customization and insights gained from customer interactions, among other things.
2. SpeechText. AI API
Speechtext AI APITrack this API enables applications to transcribe audio from media files into text. The API can recognize multiple speakers in many languages and add word-by-word timestamps, punctuation, and casing to transcription results. Its speech recognition technology enables users to improve the accuracy of automatic transcription for industries such as finance, healthcare, legal, IT, HR, and others. SpeechText AI supports almost all common media file formats and can transcribe audio/video files stored on a hard drive or files accessible over public URLs ( HTTP, FTP, Google Drive, Dropbox, etc.).
3. Scale AI API
The Scale APITrack this API allows users to access on-demand human workforce for different categories of tasks. The innovative solution that has been dubbed the “API for Human Labor” is essentially a scalable interface for outsourcing labor to on-demand workforce. Users can apply the API to perform a variety of tasks within the categorization, transcription, and phone calls functions.
4. Rev.ai API
Rev.ai provides speech recognition, human transcription, and speech-to-text transcription services. The Rev.ai APITrack this API provides speech-to-text recognition services that can make audio and video content searchable and accessible. Rev.ai automatically adds punctuation and capitalization to transcripts to make them easy to read. It can recognize multiple speakers and attribute text to each. Rev.ai Streaming API is a new service that allows real-time audio transcription.
5. IBM Watson Speech to Text API
The IBM Speech to Text APITrack this API leverages Machine Learning for grammar, language structure, and the composition of audio and voice signals to automatically transcribes human speech to text. Developers can use this API to add speech transcription capabilities to their applications. The service continuously updates and refines its transcription as it receives more speech.
6. GoTranscript API
The GoTranscript APITrack this API can add transcription, translation, captioning, and subtitling features to applications. With the API, developers can implement languages, comments, turnaround times, number of speakers, and transcription file formats into applications.
7. Bible Brain API
The Bible Brain APITrack this API offers access to the Bible via text, audio and video. API methods are available to retrieve languages, countries, bibles, audio timing and to search bible for a word.
8. Speechmatics API
Speechmatics provides its cloud-based services on a range of languages. The Speechmatics APITrack this API offers a transcription Platform to integrate with existing applications. It supports different audio and video formats such as MP4, and WAV. This REST API returns data in the JSON format and uses Token for Authentication.
9. Liopa-LipRead API
Liopa technology provides visual speech recognition services that decipher speech from lip movement using state-of-the-art deep learning. The Liopa-LipRead APITrack this API enables applications to read a user’s lip movements to verify if they said a sequence of digits. The API is useful for augmenting audio recognition and supporting biometrics.
