## AssemblyAI

AssemblyAI builds speech AI models and the infrastructure to run them, aimed at developers and product teams adding voice to an application. Its core offering is speech-to-text: an asynchronous API for pre-recorded audio, a realtime API for streaming and voice agents, and a synchronous API for short clips and dictation. The company's flagship accuracy model is marketed as top of independent benchmarks, with strong speaker diarization and native code-switching across dozens of languages.

On top of transcription, AssemblyAI offers a Speech Understanding API that layers tasks such as summarization, sentiment, topic detection, PII redaction, content moderation and guardrails onto transcripts. It has also released its first text-to-speech model, AssemblyAI-TTS-1, built for voice agents on live calls, plus an LLM Gateway for routing model calls and a Dictation API. Models can run on AssemblyAI's managed inference cloud, or self-hosted in a customer's own VPC or on-premises environment.

Pricing is pay-as-you-go after a free trial: for example, pre-recorded transcription is billed per audio hour, with optional add-ons such as speaker diarization, keyterms prompting and medical or veterinary modes priced separately. Enterprise plans offer custom rate limits, higher concurrency and compliance features including SOC 2 Type 2, HIPAA and GDPR.

**Pricing & Plans:** Free trial to start, then pay-as-you-go per audio hour and per add-on feature — for example around $0.15/hr for the Universal-2 model and around $0.21/hr for the more accurate Universal-3.5 Pro model, with extras like diarization billed individually. Enterprise and custom-rate-limit plans are available via sales.

- **Async, realtime and sync speech-to-text:** Choose pre-recorded transcription for files, a realtime API for live streams and voice agents, or a synchronous endpoint for short clips and dictation.
- **Audio intelligence and Speech Understanding:** Layer summarization, sentiment, topic detection, PII redaction, content moderation and guardrails onto transcripts without building your own models.
- **Text-to-speech for voice agents:** AssemblyAI-TTS-1 is trained on real phone calls for natural, low-latency speech, targeted at IVR and voice-agent use cases.
- **High accuracy with diarization:** Flagship models emphasise exact transcription, speaker labels and native code-switching across many languages, supported by published benchmarks.
- **Flexible deployment:** Run models on AssemblyAI's managed cloud with unlimited concurrency, or self-host in your own VPC or on-prem for full data control.

**Strengths:** One API family covering transcription, understanding and text-to-speech; Transparent per-hour pay-as-you-go pricing with a free trial; Self-hosting option for teams with strict data-residency requirements; Strong accuracy and diarization performance backed by published benchmarks

**Limitations:** Costs scale with volume and add-ons can raise the effective per-hour rate; Some advanced features are model-specific and not available on every model; Heavier product surface than a simple transcription API may be overkill for basic needs

## Vatis Tech

Vatis Tech is a speech-to-text company that offers the same underlying models two ways: a web transcription platform for individuals and teams who want to upload a file and get text back, and a developer API for products that need to transcribe audio at scale. The platform accepts drag-and-drop files, pasted links and live browser recordings, handles both audio and video formats, and exports clean text as TXT, DOCX, PDF, SRT or VTT after editing in the built-in editor.

Its differentiation is accuracy on real, messy audio rather than studio recordings, backed by an independent benchmark from the University of Bucharest that scored seven transcription systems on over 126 hours of Romanian speech. Vatis finished in the top two overall, ahead of Google's Chirp on every test set in the study and best in class on broadcast news and podcasts. The company is best known for Romanian, where its models are trained on proprietary data, but it publicly markets 50+ languages and the same model family for English, Spanish, French, German, Italian, Portuguese, Arabic, Japanese, Korean and more. A streaming model for real-time Romanian voice agents and contact-centre use is in development through an early-access programme.

Pricing is split between subscriptions and usage. The transcription platform runs on monthly hour buckets (Basic, Standard, Pro) with overages at €5 per hour and yearly plans billed as ten months for twelve. The asynchronous API is pay-as-you-go at €0.22 per hour of audio with €10 of free credit on new accounts. Audio Intelligence — summaries, chapters, topics, sentiment and PII redaction — is billed per token on top of the underlying transcription. Enterprise agreements cover volume discounts, SLAs, unlimited concurrency, dedicated support and on-premise deployment; the compliance posture advertised is GDPR compliance, ISO 27001 certification and SOC 2 Type II in progress.

**Pricing & Plans:** Free 10 minutes with no signup, then subscription plans: Basic €10/month (10 hours), Standard €27/month (30 hours) and Pro €89/month (100 hours), with extra hours at €5/h. The async Speech-to-Text API is €0.22 per hour of audio, pay as you go, with €10 of credit on new accounts; Audio Intelligence is metered separately by token. Enterprise is custom-quoted.

- **50+ languages at 95%+ accuracy:** Upload audio or video by file, link or live browser recording. Vatis accepts MP3, WAV, M4A, FLAC, AAC and OGG audio plus MP4, MKV, AVI, MOV and WebM video, and typically returns a 1-hour file in under a minute.
- **Speaker diarization, summaries and chapters:** Interviews, meetings and podcasts get automatic speaker labels, extracts of key quotes, chapter markers and a summarised version of the recording, all generated from the same transcript.
- **Developer API with pay-as-you-go pricing:** The asynchronous Speech-to-Text endpoint supports payloads of any length and returns diarization and word-level timestamps. Every new account gets €10 of credit for building against the API.
- **Translation and subtitle generation:** Turn a transcript into subtitles or captions in another language without leaving the platform, and export timed files as SRT or VTT for video workflows.
- **GDPR, ISO 27001 and enterprise controls:** Vatis states GDPR compliance and ISO 27001 certification, with SOC 2 Type II in progress, plus enterprise options such as private cloud and on-premise deployment, SLAs and unlimited concurrency.

**Strengths:** Strong independently benchmarked accuracy, especially on Romanian audio; Genuinely generous free tier: 10 free minutes plus €10 of API credit; Wide input and output format support, including SRT and VTT for subtitles; Transparent published API pricing at €0.22 per hour, a fraction of Google's rate

**Limitations:** Subscription hours are billed monthly and unused subscription balance expires when a plan lapses; Real-time streaming is still in early access and limited to Romanian; The headline accuracy claim is strongest in Romanian — other languages are marketed as broad but without the same public benchmark detail; Audio Intelligence analysis is priced per token on top of transcription, adding up quickly at scale
