In an environment where time, compliance, and data accuracy directly impact outcomes, transcription platforms must do more than just convert speech to text. They must integrate seamlessly into broader content, legal, and operational workflows. Rev, Temi, and Sonix represent three distinct approaches to transcription: manual precision, entry-level automation, and enterprise-grade AI, respectively.
Each solution offers its own value proposition across areas like turnaround time, security, language support, and workflow compatibility. However, as expectations around transcription have evolved, driven by advances in artificial intelligence, multilingual business operations, and collaboration at scale, so have the criteria for selecting the right tool.
This comparison doesn’t just evaluate pricing and speed, but how well each platform fits into a professional tech stack built for growth, security, and performance. The differences may appear subtle at first, but they carry significant weight in daily operations and long-term strategy.

The company offers a range of solutions, including both AI-powered and human-assisted transcription, to cater to diverse needs and industries, such as legal, media, education, and research.
With Rev, users can convert audio and video content into accurate, searchable text, making it easier to analyze, share, and repurpose their data. The platform also provides tools for meeting management, collaboration, and productivity, streamlining workflows and enhancing communication.
Rev offers two main types of transcription services: AI transcription and human transcription. The AI transcription service delivers 95%+ accurate transcripts in 30 minutes or less for clear audio and video files. It supports over 38 languages and is compatible with multi-channel audio formats, including FTR. Additionally, the AI transcription service includes instant summaries, key quotes, and social media copy generated by VoiceHub’s AI Assistant.
On the other hand, Rev’s human transcription service provides 99%+ accuracy for challenging audio, such as recordings with background noise or heavy accents. The median turnaround time for human transcription is 16 hours, with options for verbatim transcripts, rush service (5x faster), and customizable timestamps. Rev combines its world-leading ASR technology with a network of over 72,000 professional transcriptionists to ensure the highest quality results.
Rev Notetaker is an innovative tool that automatically joins meetings on platforms like Zoom, Google Meet, Microsoft Teams, and Webex. It generates real-time transcripts with speaker identification and diarization, captures screenshots of shared content, and provides basic summaries with action items and keywords for free.

VoiceHub is Rev’s unified workspace that offers:
Rev caters to specific industries and use cases with specialized features, such as:
Legal Solutions:
Mobile Capabilities:
Security & Compliance:
Rev offers two transcription options: human transcription for higher accuracy and AI transcription for faster, lower-cost results. Both come with basic editing capabilities and Dropbox integration. Here’s a summary of their pricing:
Human Transcription: Billed at $1.99 per minute, this service includes 99% accuracy with delivery in 12 hours or less.
AI Transcription: Priced at $0.25 per minute, this automated service provides transcripts in about five minutes, with an advertised 95%+ accuracy. Language support is currently limited, with broader availability noted as “coming soon.”
While Rev is decently priced, it’s important to remember that this cost is for lower accuracy and fewer transcription languages. We cover this in detail in our Rev review.
Temi is an AI-powered transcription service that converts audio and video files into accurate, searchable text. The platform caters to a range of users, including journalists, podcasters, researchers, and content creators, streamlining their workflow and saving time on manual transcription.
However, before you sign up with Temi, it’s important to note that it is a reskinned version of Rev. It uses Rev’s transcription API and provides the same level of accuracy, at the same price, with much fewer features. As a result, we cannot recommend Temi as it comes at a higher price than Sonix and lacks features compared to the two other tools on this list. We cover this and more in our Temi review.
Temi’s core transcription engine utilizes AI algorithms to convert speech to text rapidly. The service supports a wide range of audio and video formats, including MP3, MP4, and WAV, making it compatible with most recording devices and software.
The AI transcription delivers 90-95% accuracy for clear recordings, with turnaround times as fast as a few minutes, depending on the file length. Temi automatically detects and labels different speakers, while also timestamping each word for easy navigation and synchronization with the original media.
Although background noise, strong accents, or overlapping speech can impact accuracy, Temi’s editor allows users to correct any errors and refine the transcript to their liking.
Temi’s transcript editor offers a seamless experience for reviewing, editing, and annotating transcripts:
The platform also enables users to share transcripts by generating shareable links or inviting collaborators via email to edit in a centralized workspace.
Temi offers an API for developers to integrate its speech recognition capabilities into their applications. The API supports various file formats and outputs, including JSON, .docx, .pdf, and direct links to the editor. Pricing for API usage is consistent with the web-based service at $0.25 per audio minute, with a 10-minute file being transcribed in under 3 minutes.
Additionally, Temi integrates with Zapier, allowing users to automate workflows and connect the transcription service with hundreds of other apps and tools.
Temi has a flat pricing of $0.25 per minute or $15 per hour, same as Rev and higher than Sonix.
Rev offers two transcription options: AI transcription with 80-90% accuracy for clear audio and human transcription with 99%+ accuracy for more challenging recordings, such as those with background noise or accents. Rev’s hybrid model combines advanced speech recognition technology with a network of over 72,000 professional transcriptionists to ensure high-quality results.
Temi’s AI-powered transcription engine delivers 90-95% accuracy for clear audio files, with a turnaround time of just minutes. However, background noise, strong accents, or overlapping speech can impact the accuracy of Temi’s transcripts.
Sonix consistently achieves 99%+ transcription accuracy across 53+ languages and dialects, even in the presence of background noise and accents. Sonix’s advanced AI algorithms and deep learning models enable it to handle challenging audio conditions while maintaining industry-leading precision.
Rev’s VoiceHub platform offers a unified workspace for teams, featuring an interactive transcript editor with version control, bookmarking for key moments, and collaborative annotations. Additionally, Rev’s Meeting Hub provides centralized access to meeting notes and transcripts across teams.
Temi’s transcript editor includes an embedded media player that syncs audio/video playback with text highlighting for real-time review. Users can highlight important sections, add comments and notes for collaboration, and share transcripts with team members via shareable links or email invitations.
Sonix streamlines collaboration with team folders, allowing users to share transcripts with granular permissions and add comments for seamless teamwork. Sonix also integrates with popular tools like Zoom and Adobe Premiere, enabling users to incorporate transcription into their existing workflows.
Rev’s pricing varies depending on the service type, with human transcription starting at $1.99 per minute and AI transcription at $0.25 per minute. Rev also offers subscription plans for its VoiceHub platform, ranging from $14.99 to $34.99 per month, with enterprise plans available for high-volume needs.
Temi provides straightforward pricing at $0.25 per audio minute, with no subscriptions or hidden fees. Users can opt for a pay-as-you-go model or add funds to their account for uninterrupted service. However, as mentioned earlier, Temi is charging the same as Rev but with much fewer features.
Sonix’s pricing starts at $10 per hour for its Standard plan, which is ideal for occasional users. The Premium plan, priced at $22 per user per month plus $5 per hour, offers a 50% discount on transcription and additional features like advanced sharing and increased upload limits. Sonix also provides custom enterprise plans for organizations with high-volume needs.
