AI-Powered Voice Transcription

Convert Recorded Speech into Readable Text

Replaying an entire meeting simply to locate one important comment can waste valuable time.

Through the compatible app, the Calthic AI Smart Voice Recorder can convert recorded speech into written text, making conversations easier to search, review, edit, and organise.

This is useful for:

• Business meetings
• Lectures
• Interviews
• Client discussions
• Project briefings
• Brainstorming sessions
• Voice memos
• Research
• Training sessions
• Personal reminders

Text-based records also make it easier to copy useful information into documents, reports, study notes, and task lists.

Transcription accuracy can vary depending on background noise, speaker clarity, accents, vocabulary, recording distance, and app or service availability.

Translation Support for Up to 189 Languages

Make International Conversations Easier to Understand

The Calthic AI Smart Voice Recorder supports transcription and translation workflows across up to 189 languages through its connected software platform.

This makes it a useful companion for:

• International meetings

• Overseas travel
• Language learning
• Global interviews
• Cross-border customer calls
• International conferences
• Study and research

Record a conversation, generate a transcript, and access translated text through the compatible app.

Language availability and real-time functionality may depend on the app version, network connection, account type, and supported service plan.

Intelligent Meeting Summaries

Understand the Main Points Without Reviewing Every Minute

Long meetings often contain only a small number of decisions, actions, or important conclusions.

The Calthic AI Smart Voice Recorder can help identify central topics and produce condensed summaries from compatible recordings.

Instead of reading a full transcript from beginning to end, you can quickly review:

• Main discussion points
• Decisions
• Action items
• Questions raised
• Follow-up topics
• Important statements
• Project updates

This can reduce the time spent producing meeting notes and make recorded information more useful after the conversation ends.

Automatic Mind Maps

Turn Complex Discussions into a Clear Visual Structure

Some information is easier to understand when it is organised visually.

The compatible Calthic app can generate mind-map-style layouts that divide a recording into central topics, supporting ideas, and related points.

Mind maps can be especially useful for:

• Revising lectures
• Planning projects
• Reviewing brainstorming sessions
• Organising interview findings
• Understanding long discussions
• Preparing presentations
• Creating study notes

The Calthic AI Smart Voice Recorder helps move information beyond a simple audio file by presenting it in a more structured format.

Dual-Microphone Audio Capture

Hear More of the Conversation with Panoramic Recording

The Calthic AI Smart Voice Recorder features a dual-microphone system designed to capture voices from a wider surrounding area.

This makes it suitable for recording:

• Table meetings
• Classroom discussions
• Interviews
• Group conversations
• Conference calls
• Training sessions
• Personal voice notes

The microphone arrangement helps collect speech from different directions, reducing the need to place the recorder directly in front of one speaker.

For the clearest results, position the device close to the conversation and avoid covering the microphones.

AI-Assisted Noise Reduction

Improve Speech Clarity in Busy Environments

Background noise can make recordings difficult to understand and reduce transcription accuracy.

The Calthic AI Smart Voice Recorder uses active noise-reduction processing designed to place greater emphasis on speech while reducing unwanted surrounding sounds.

It can help manage common noise such as:

• Office ambience
• Air-conditioning
• Light traffic
• Room echo
• Keyboard sounds
• Background conversations
• General environmental noise

This provides cleaner playback and gives the transcription system a clearer audio source to process.

Extremely loud, crowded, windy, or echoing environments may still affect recording quality.

High-Quality WAV Audio Recording

Preserve Speech with Clear Digital Sound

Recordings are saved in WAV format using a stated 256kbps bitrate and 48kHz sample rate.

These settings are designed to retain clear vocal detail for playback, transcription, and long-term reference.

Audio Specifications

• Recording format: WAV
• Recording bitrate: 256kbps
• Sample rate: 48kHz
• Microphone system: Dual microphone
• Noise processing: AI-assisted active noise reduction

WAV is a widely recognised audio format that supports high-quality recording and convenient playback on many compatible devices.

Magnetic Smartphone Attachment

Keep the Recorder Securely Positioned for Calls and Meetings

The magnetic design allows the Calthic AI Smart Voice Recorder to attach to compatible smartphones or magnetic accessories.

This keeps the recorder close to the audio source and helps create a compact setup for:

• Telephone conversations
• Online meetings
• Conference calls
• Voice messages
• Mobile interviews
• Remote consultations

For phones without built-in magnetic compatibility, an appropriate magnetic case or attachment ring may be required.

One-Button Call Recording

Start Capturing Important Conversations Quickly

When a conversation begins unexpectedly, navigating through complicated menus can result in missed information.

The Calthic AI Smart Voice Recorder uses straightforward controls that allow recording to be started quickly.

This can help capture:

• Client instructions
• Supplier discussions
• Remote meetings
• Appointment information
• Project updates
• Important telephone conversations

Always obtain any consent required before recording another person. Laws governing call and conversation recording vary by location, purpose, and how the recording will be used.

iOS and Android App Compatibility

Manage Recordings from Your Smartphone

The dedicated mobile app provides access to the recorder's intelligent features from compatible iOS and Android devices.

Through the app, users may be able to:

• Access saved recordings
• Generate transcripts
• Review translated text

• View mind maps
• Rename and organise files
• Search recording content
• Share selected information
• Manage device settings

The mobile workflow helps keep recordings and written information organised in one convenient place.
