Mike for Telephone TTS Voice Generator

Hear the telephone effect before generating your menu

These two recordings use the same sentence, preset and synthesis settings. The first is the dry source. The second adds a 300 Hz high-pass and a 3,400 Hz low-pass to reduce the low and high frequency extremes. Listen for the change in vowel body and consonants at the same device volume.

Apply telephone filter is on by default in the generator above. Turn it off and render again to compare your own script. Both preview and download follow that choice, and Copy Link saves it. The filename ends in phone or dry so the two versions are easy to identify.

What the preset and the filter each contribute

The Mike for Telephone preset selects a SAM voice recipe: Speed 86, Pitch 58, Mouth 95 and Throat 105. Those values change how the speech is synthesized. The filter is a separate processing step applied to the generated waveform; changing Mouth or Throat alone does not provide the same effect.

This is a telephone-style sound for a game, intercom scene or video. It does not reproduce the original Microsoft Mike engine, add line noise, or encode audio for a real telephone service. The export remains mono 22,050 Hz, 8-bit PCM WAV. If an IVR platform asks for 8 kHz mu-law or another codec, use its specified conversion process.

Build a four-file menu that can be interrupted

Copy these four scripts into the text box on separate lines. Choose the filter state, then open Batch line rendering and download four WAVs. Rename the numbered files using the names below. Keeping each action in a separate clip lets a game or player stop the prompt when a choice is made.

Keep menu choices clear through the filter

Start at the preset values and generate the shortest option first. If Press one for platform status feels rushed, increase Speed from 86 toward 96. A larger value makes SAM slower. Keep Pitch, Mouth and Throat unchanged while judging the pacing.

Spell menu digits as words. For an access code, write the intended spoken form explicitly: four oh four differs from four hundred four. If a name loses clarity through the filter, compare a phonetic rewrite against the dry version before changing the voice identity. The pronunciation guide provides a focused method for those tests.

Place pauses and check the complete sequence

Import the four clips into your editor or game and place the gaps there. Punctuation shapes a spoken phrase but does not set an exact pause in milliseconds. Test greeting, option one and option two as a sequence; a clear individual clip can still become hard to follow when the choices are too close together.

Keep a dry copy if you plan to add noise, music or reverb. Listen to the finished sequence on a small speaker and confirm that one and two remain distinguishable. For a real phone system, also verify the platform's required codec, sample rate and playback behavior; this page produces the creative source audio.

Which voice engine is used here?

This tool uses sam-js, a JavaScript port of Software Automatic Mouth. Microsoft Sam and Software Automatic Mouth are different speech systems. Labels such as Mike, Mary and RoboSoft identify this site's parameter presets; they do not load the original Microsoft or SAPI4 voice binaries.
